I've had the Baron/Bonanza Professional combo since day one and have had no issues whatsoever with glideslope/glidepath capture and stable descent in 2020. I recently (finally!) moved over to 2024, installed the '24 versions and am now also struggling with capture as well.
It's probably 50/50 for me as to whether I'll capture the glideslope in the first place, but if I do I've also found that even when captured the AP seems to struggle stabilizing, oscillating between above and below path until finally damping down. If I put in the final notch of flaps after stabilizing, it will once again oscillate before either stabilizing or me giving up and hand flying the approach.
Again, these are issues I never had with the 2020 versions. For reference, long time simmer and RW GA pilot. We all make mistakes, but I'm pretty sure this isn't user error. I'm using the TDS units exclusively.
