Account disappeared after a transfer

My account PooPoPoPoPoPoooo linked to gmail address has disappeared after a transfer to new device, in the guild (GHOUL :zap: ITA) they told me that the message he abandoned appeared and they no longer find personal chats with the same account. How can this happen if this account is connected to Google Play? Please help me recover my account and the time I spent on this game. Thank you

No response after 3 days, this is a serious bug … any account with a cross-device transfer could disappear. Why is it overwritten? How can I overwrite something uniquely linked to a Google Play address? Please help me in some way to recover the account, also you could use this report to fix this bug! Thank you
