Migo Error “Failed, Device Is Not Available” Blocks Access

I use the Migo application on my Vivo V25 and today around 12:00 I suddenly started getting the error message “Failed, device is not available”, and it seems that my device has been banned without any explanation. There is around 10,000 in my Migo account and I want to continue using my account and my device as before. I request that my device be unbanned on Migo, that my access be restored, and that my account balance be protected without any loss. I also request a clear explanation of why this situation occurred.
