As you may know by now, Bandai is currently checking for corrupted data in Tamagotchi Meets and preventing those users who carry corrupted data from connecting the app.
They will soft ban only the Tamagotchi Meets device that contains corrupted data. If you have another Tamagotchi Meets, it will connect without any problem (if it doesn't contain corrupted data).
If your Tamagotchi Meets is prevented from connecting to the app, you will get the message below.
Some of you might receive the below message IF ONLY you are idle for certain period. Don't panic when you see this message and think Bandai banned your Tamagotchi Meets ^^
