I also had a problematic upgrade: Dragonfish to EE went well from the OS point of view and all my data is intact, but the app migration didn’t. I reverted, using the boot environment options, and I will wait until further updates to EE have occurred. I may have jumped the gun, wanting to be a “general” user a bit sooner than I should have.
From a faultfinding/being able to assist point of view, regrettably I’m not yet in a position to go back to EE and try again in order to generate bug reports - too exhausted from the last couple of days of effort trying to sort out problematic apps! Frigate was one app and Motioneye, a custom app, was another: both demanding significant CPU resources under EE (80-100%) compared with DF (30-40%).
(I realise this doesn’t help but I wanted to add moral support, and here’s a previous post describing a bit more).
