Same issue here. What’s weird is they *used* to work, but one ran down its battery and when I started it up, for some reason I hit the reset button. Now it just endlessly repeats “welcome to Reolink” in ten languages. I can hit the plus to add it, scan the QR core or input the UID directly, and either way it just endlessly welcomes. I tried resetting the other one which was working earlier today, and now it’s a brick, too. The initial setup two years ago was incredibly smooth and painless, but I think that either the app no longer supports the older devices or the hard reset puts them in an unrecoverable state.
