Hi Everyone. I've been experiencing some glitches with my Phantom 4 Pro+ since a firmware upgrade after the green screen problem a little over a yaear ago. All the issues where small at first, a warning about max alititude reached when the drone first took off and a constant message to upgrade the flying database no matter how many times I did it,  leading up to a temporary fly away the other day and two total total dropouts today. Also, FWIW, the drone lost signal at apr. 500 meteres away the other day and went into fly home mode, but stopped well short of the landing point and started to land itself in the bush. In short, I've had increasingly common and more serious glitches Today, after my flight, I put the drone away and retuned home and the controller started up ok and then logged me out and now won't reconnect to my home network. (the network is working fine) The drone apears to power up normal, but I can't get a connection to it either. FWIW, it's probably done less than 50 flights. Also, (generally) if I've had a glitch or two at startup, until yesterday, everything was then fine for a flight and I managed to get my work done. Any ideas to reset things or start over ? Can the controller be manually re-set ? Cheers if you can help.

Update - I got the controller back online and logged in. After a quick test flight everything seems fine, but after all the glitches it's going to be hard to trust this thing.
