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). ![Screen Shot 2021-03-10 at 2.58.44 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/c/1cbaa7ee13cacccf174324015d11790bd957030a.png) ---

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 David ---
