I've been flying flight sims since 1983. Using FSX, P3D, MSFS 2020 and now MSFS 2024. Using the default 737 MAX and a flight plan created using default planner, Simbrief or LittleNavmap I get the same results when doing a ILS approach. Everything is set correctly. Course and frequency. I get the red indicator showing the glideslope and watch as it slowly goes down. The problem is the aircraft doesn't follow the glideslope. It continues to fly the intercept altitude and doesn't lose altitude as it should. 
Is this a bug with the MAX or am I doing something wrong?

Thanks in advance.

Screenshot of your PFD at glideslope intercept?

 

Autopilot in Approach mode?

I FOUND IT!!!! After three months of flying the MSFS 737 MAX I think I have it figured out. At least it worked this time I have been short hops from KTPA to KRSW runway 06 and could never capture the glideslope. I was using 3000 ft. as the capture altitude which Flight aware has and other sites also. I just happen to check the charts in MSFS flight planner and to my surprise it showed 2400 ft. I just completed a flight with the new capture height an a perfect result. Who would have guessed? That's why it would work at some airports and not at others. Always check the charts in sim flight planner.

That is not the reason.  You can capture an ILS at ANY altitude as long as you are in range.  Make sure you approach the ILS from below and you have the approach mode armed.

That's my point. At 3000 ft. I was too high to capture the glide slope. I tried 2800 feet and still did not get the slope.

Not me, because that's sure not how the airplane is supposed to work 😉.  But whatever makes it happen I guess!

As stated, if you are above the glideslope when you hit the approach button, you will keep flying happily along at the same altitude. 😉

So true.

Capture the ILS further away if you want to capture it higher.

While I'm glad your solution worked, it doesn't make sense as you said that you flew through the GS.

Never mind.
