If Eufy can’t fix the issue, best solution is revert back to an older version of the app where your issues aren’t happening. You can sideload older versions from sites like APKMirror.com or APKPure.com. I have used both of these sites for several years without any issues.
Note: APKMirror will usually show you 2 apps with the same version number. One will be only the Eufy Security app, the other will be a bundle of apps that includes Eufy app. Don’t select the bundle version or you can get a bunch of other apps in your download that you don’t want.
