this message keeps popping out even when I'm not dealing with this token (for instance, when I try to call some functions on the bscscan's page of a completely different token, it shows me the exact same message),
Have you tried Metamask on your mobile phone? does the notice always come out like when you use metamask in the browser? if so, there may be something wrong with your wallet settings. try logging in qr scan on your mobile phone. if still the same . try to import your wallet in new metamask account . if it's still the same, the problem is definitely the token then ask their community.
