This just sounds like an error pasting your keys?
I'm unsure how you think this is a Adguard issue.
Is there a way the developers could reproduce this?

@guandasheng Are you able to try the new edge build discussed in https://github.com/AdguardTeam/AdGuardHome/issues/7856 and see if that resolves the issue for you?

Thanks!
