I live in a multi-Roku house and since the last update to the Roku Android app, it keeps crashing when going to the Devices screen or I try to select a device from the Remote screen. I've tried a OnePlus 8 Pro, a OnePlus 6T and a freshly installed version on a Samsung Tab S6. All exhibit the same problem, though on some I can't even get into the Remote screen.
Same happening for me as well as my wife's device. I am on a Pixel 3a and she is on a Pixel 4. We couldn't find one of our remotes (we have 6 rokus of differing types) and I went into the app, went to devices and it closed out. Will probably look on apkmirror for the old release and sideload it.
