No push notifications are shown.

Hello. Our team uses FCM to send push notifications.

The system has been working for several years without any problems. Recently, however, push notifications have frequently failed to appear.

Checking the logs shows that push notifications are reaching the device, but there seems to be a problem with the device token.

Does someone know how can I fix it?
