@andora did you try this at all? I’m logged into Bitwarden on my unrooted Android (S22 Ultra) but I have my older LG here that is rooted. The adb backup on the S22U and the restore on the LG didn’t seem to work as I didn’t have Bitwarden installed on my LG. Trying to figure out how to restore from Google One backup and it looks like I will have to wipe the LG to start the restore from Google One…
Edit - made my own post and was able to retrieve the vault-export json through the Firefox extension. Doesn’t solve the android query I had but this worked. Thanks to @grb!
