I don't think you'll have any problems running GO4... it's not a bloated resource-hog like FLY. The only update likely to get released now is a new version (probably late December 2025) that supports RID for Europe and the UK.
There you go again... cherry picking your quotes to support your narrative - leaving out the "...if the motor overloads or stalls during flight..."
What I've typed does not require logic nor 'interpretation'. It is a simple reiteration of DJI...
You probably calibrated the compass needlessly. Try recalibrating the remote control. There’s probably a bit of left of centre in the left stick. It might have been caused by storing with the sticks mounted.
Concur with the above. Check the Hall sensors (sticks) on the controller. It may be that the left stick is registering a very slight yaw input in one direction. Go through the controller calibration process a number of times.
Love the way you're ignoring the second part of the warning message... you know... the sentence that clearly reads "...propellers blocked or frozen...". So that'll be the drone diagnostics jumping to unfounded conclusions without solid evidence...
