I've since learned that LNM will not show the flight plan magenta line in its MSFS 2020 top menu rendering, if any waypoints on that flight plan have names longer than 7 characters. I went back and altered the flight plan, with different and shorter waypoint names this time. Presto, the magenta line was back, once I was up flying in the sim. But meanwhile, my guess is that this waypoint name glitch also happens in MSFS 2024. If so, then hopefully the solution will also be the same.

After downloading this latest version, I suddenly encountered error messages when attempting to save new flight plans in the usual LNMPLN format. "File not found" was the basic summary. In reviewing past posts here (from 2023) on this issue I saw some discussion that MS OneDrive was a likely cause and that moving all things LNM over to Google Drive did the trick. However, I have had LNM and its flight plans deep in my OneDrive subfolders all along and I've had no problem whatsoever creating and saving my LNMPLN files there -- until the update I installed today. So, what is the cause? Thanks for asking. After trying and retrying to save a flight plan to LNMPLN, I was going to post in this Forum for some advice. But then I got a popup from my Windows Security/Protection History background process, saying that it had blocked LNM from making changes within a Protected Folder. Accordingly, I went into Controlled Folder Access Settings/Allow an app through Controlled folder access/ and then answered YES to User Account Control, which brought me to the next screen with the box "+Add an allowed app" . Once I clicked on that, I was able to add Littlenavmap.exe to that Allowed list. Then, going back into the LNM app, I was able to save my flight plan in LNMPLN format normally, in the location I've used all along. Problem solved. I hope anyone else having the same glitch I've reported here can solve it in the same way.

Thank you Alex, I knew of MSFS limitations and now I've added this one. I will proceed with tinkering with flight plans manually in the sim as best I can, with my LNMPLN files as dependable backups. ~John

Update to above posting: I actually cannot resume my LNM flght plan in the sim, as I described above. Back in LNM, once I completed the first leg of the flight, I saved the flight plan as an LNMPLN file, hoping the sim would later allow me to load it. That would have put my aircraft on the waypoint runway at the next stage of the flight. However, the sim only recognizes and loads PLN files and not LNMPLN files. In this instance, the only file I could load was the original complete flight plan in PLN form. The sim drop-down menu showing this full flight plan did not have any waypoints showing this time. So I had to zoom in on the sim map (showing the full flight plan) and click on the waypoint airport manually as the new "Departure". This tedious, but certainly doable. I still don't know how to work with LNM and MSFS 2020 together to allow me to resume an established flight in the sim without all the above manipulations. Any advice would be appreciated.

Yes, as you suggest, LNM does do that. I had assumed incorrectly that LNM would automatically drop me into the next active leg when I resumed the flight plan in the sim. However, the workaround I've found is in the sim -- not in LNM: When I reload the LNM flight plan there, the entire plan is shown with Departure airport and Destination airport. As you know, each of these points has a dropdown menu with the various arrival/departure points along that flight plan available. I simply select the new departure point which is the beginning of the next leg, and the sim places my aircraft there, ready to take off. LNM, meanwhile, proceeds to jump to that point along with me. All good. Thanks for your post.

In LNM, under Tools/Options/Startup and Updates, I have "Load last used flight plan" checked. Then, after creating a simple 3-leg flight plan and exporting it to MSFS, I launch the flight sim and load the LNM flight plan and begin my flight. I complete the first leg and then exit the sim with the intent of returning to resume the flight later. I've seen online advice saying how LNM automatically saves the progress of a flight plan when exited. However, when I do return later and relaunch LNM, it does reload that last used flight plan but it displays it without the progress I've made. Then, when I relaunch the flight sim and load that flight plan, sure enough it has me back at the beginning and I have to start over. What steps am I missing?
