[Solved] Sandbox Error target Sandbox version

I am trying to upload a new app the the Android store and get the error below.
Any help please…Surely I dont have to install and learn Android Studio to fix this

Invalid value for the ‘android:targetSandboxVersion’ attribute in the AndroidManifest. If publishing an Instant App, consider using the Android App Bundle to add this attribute correctly.

Hi @towball :wave:

Apologies for the delay getting back to you about this.

Did you manage to get your app published?

If not, can you send a screenshot of the error message so that we can see where in the process this error is occurring?

Thanks!

Ok now thanks and cant remember how I fixed it…
