For some odd reason on my system, the ASOBO updates (at Checking for Updates) will DL just fine at any speed my router can do.
But on my system, from the Content Manager, all downloads have to run very slowly at 10Mbits/s or slower or they will hang. Don't know why there is such a difference.
Not a big problem because the Content Manger files are all very small vs. the monthly MSFS updates.
But something to watch out for if you have problems downloading.
