I have my app installed on the device with version 2.3.6 2.

I created the new version of it: 2.3.7 1.

And it says I can downgrade the app if I want instead upgrade...?

What could be the problem?

CodePudding user response：

Did you increase the versionCode as well as that versionName you showed?

See https://developer.android.com/studio/publish/versioning

The versionName has no purpose other than to be displayed to users.
