Hi all  
I need a solution for the use case when google play claims wrong cerificate used.  
Probably because copying the app several time… (but i am not sure)  
Is there anything written around this ? (i cant find it)

Hi @stefansladdeneng1, I hope I understand your question correctly,

have you read the chapter about app signing? You find the app key under the app settings at the bottom (“Keystore zip” / “Android keystore”). In short: in Thunkable klick on “Export key zip” and import this zip-file in Google Play Store → App signing.

Hmmm In this case i am talking about the certificate - not keystore.  
I do get a certificate displayed in Google play Store - Stating it is wrong  
And i do get a certificate displayed stating it is the correct one to use.

So how can i fetch this correct one and implement it in the APP?  
(The upper is correct - and the below one is wrong)
