alright so i've been using my M300 with the H20T for about 8 months without any real problems and yesterday i pulled it out for a routine inspection job and the gimbal is just... tilted. like maybe 4-5 degrees off to the left when it initializes. the horizon in the feed is noticeably crooked.

i've done the gimbal auto calibration through the DJI Pilot app like three times, tried it on two different aircraft actually because we have two M300s at the company, and it's doing the same thing on both which is weird. so either both gimbals got bumped somehow (unlikely) or it's a firmware thing. we did update to the latest firmware two days ago and that's the only thing that changed as far as i can tell.

the payload itself doesn't look physically damaged, no obvious reason for it. anyone else seen this after a firmware update or am i just going crazy

yeah there was a lot of noise about the last M300 firmware update breaking gimbal calibration on some units. not universal but definitely not just you. DJI support has been asking people to roll back and then redo the calibration on flat ground with the aircraft completely level before updating again. tedious but it seemed to fix it for most people i've seen posting about this.

on the H20T specifically there's a manual horizon calibration buried in the advanced settings that's separate from the auto cal. most people dont know it's there. that one actually adjusts the roll offset directly. the auto cal doesn't always fully correct a persistent offset, it's more for pitch and yaw drift. might be worth digging around in there before you start panicking about firmware rollbacks
