You uploaded an APK that is not signed with the upload certificate

Questions about Thunkable

I’m trying to add my downloaded .apk file to the Google Play Console and getting this error:

“You uploaded an APK that is not signed with the upload certificate.” I generated an upload certificate in Android Studio after this happened but I’m not sure where to apply it. Do I do that in Thunkable somewhere? Do I do that on the Google Play Console?

I have a .jks file but when I try to import that into my Thunkable project as a keystore, it won’t let me (it’s greyed out in the Finder).

Hi, I have the same issu you reported (it looks nobody answered to you though)
I got the same text al Google Play Console. The differece is that I do not know what is Android Studio or a .jks file (I am not a IT guy at all).
Is there any way I can make Thunkable “writes” the former certificate number at the .apk file for my new version?
Thanks
