New address detected message(s)

Since yesterday when i try to collect rewards on various daps i get this message “New address detected! Click here to add to your address book”. Is there anyway to validate if the address i am expected to add is actually related for example to Pancakeswap?

In an other Telegram group someone suggested this was the result of a Metamask update. I doubt that is true as i use Metamask for years and i never had this before. I hope someone recognizes this.

The only thing I have in mind is that the dApp is a bridge chain or crosschain exchange that see your new added chain???
Just a guess but my buddy advice do not authorize that until you clarify better… Can you see the address of this new phantom wallet? Is same of your MM wallet?

PS what about Token AllowanceTracker or wallet permission check tool? Is there any smart contract that has Unlimited authorization on your wallet?
