Reconnect Pinterest warning
Pinterest stopped accepting your connection, so no pins are being made until you reconnect.
Reconnect Pinterest
This warning means Pinterest turned down EverySqueeze's sign-in for your account. Usually the access was removed on Pinterest's side, or Pinterest refused to renew it. Until you reconnect, no pins are made.
To fix it, go to Settings → Accounts and platforms → Pinterest and choose Reconnect. You'll sign in to Pinterest and approve access again, and the warning clears once the connection works. It takes about a minute.
If you don't use Pinterest anymore, choose Remove it on the same row instead. That disconnects Pinterest and clears the warning.
