Disappointed in device discovery


I need to contact support about it. I change the name on each detection by adding three questions marks to the proposed name and flip the “this is a guess” slider to off. So I think there have been a few renamed that have gone missing.
I know for sure there were four I did not rename. They all four were detected at the same time and gone the next day. I didn’t get the notice sense has sometimes given me about a device being removed with these.
Some of these happened during the time of renaming difficulty, which is still happening.
