I just ran into this today. It was inconsequential in my case, but frustrating. I was able to connect to a WiFi access point and login.
My complaint is you can't head this off in advance. You MUST just let it happen! My Mavice 3 Pro let me know, also today, that I'll be logged out in 5 days. Fine. Can I logout now and avoid being forced out? Nope. The specific instructions are to log back in AFTER being logged out. How am I supposed to plan for that when I don't know exactly when it's going to happen? Just in "5 days".
Come on, now, DJI, you're better than that. I understand periodic re-validation. But if you need to re-validate a user, give us an option to do it when we have time, before forcing the user off, so it doesn't just happen when we're about to start (and trash) a shoot!
Good thing cars don't do this, or full-sized aircraft with human pilots. Wouldn't that be fun? "You've been logged out", and the car slows to a stop on an interstate with traffic buzzing around you at 80mph. Or mid-flight over water, "You've been logged out. Re-login with WiFi." Since there's no WiFi for miles, the plane flies in a circle until it runs out of fuel.
Just wait, I guess.
