I'm from the camp that quietly flies around using the GO4 app with the latest FW and app updates with no issues. Sure there have been a couple of moments where I botched an upgrade and come to this forum for advice, but the package has been more than reliable. Litchi is not immune from glitches that were present a couple of updates ago, now resolved, and I use that as an 'accessory' when I want to fly a mission for instance.
Most of the issues presented on this forum are roughly divided into either, operators not understanding how to use their DJI product, using device platforms that are not up to the task or not reading/understanding the manual.
In your case, fly with what you have loaded and get comfortable with it before updating so that you have an understanding of how your P4A behaves to use as a reference point.
