App not installed error on android 11 device from appcenter

Question

I am working on Xamarin.Forms app. After changing targetSdkVersion to 30 and building app on appcenter with latest sdk(11.1) available, I am getting error App not installed only on android 11 device. If I change targetSdkVersion back to 29 and build the app on appcenter then I am able to install the app on android 11 device.

Got more detail when installing apk on emulator :

The APK failed to install.
Error: INSTALL_PARSE_FAILED_NO_CERTIFICATES: Scanning Failed.: No signature found in package of version 2 or newer for package "*packagename*"

Do I need to update my keystore ? if yes, how can I update it ?

Re-uploading the existing keystore on appcenter has resolved the issue — Dhruv Gohil, Jun 25 '21 at 09:29
Same thing happened to our build. Re-uploading the keystore seems to have fixed it (also disabled app bundle for the internal build, which I had enabled while troubleshooting this issue, and it remained broken until I disabled it). — Ben Reierson, Jul 05 '21 at 03:46

Re-uploading the existing keystore on appcenter has resolved the issue, worked for me too.

Same issue I faced with latest Android version. In appcenter select the app, goto settings and

remove existing keystore and upload keystore again
