After upgrading 4.x, no more Android Support

I have Upgraded my system (from 3.x to 4.x). It works fine except that I have no more Android support.
I am a registered user. Do I need to purchase a new licence for this new release ?

Thank you to tell me how to proceed.

(Sony XPeria XA2)

Android support is working OK for me, Xperia XA 2 dual sim.

Did you have “disable android package verication” option activated and “start” and “stop” greyed?
In this case, uncheck it and unchek “start android on bootup” and reboot your phone.
After launch android. You can now check all option.

Thank you for you response.
If I uncheck “start Android at startup” and “verification package” and reboot my phone, Yes, the button “Start Android” is now activated.
But Android doesn’t start. (with button or when I start an android app)

Is there system logs I can check to have more information ?

Try this possible solution: https://forum.sailfishos.org/t/4-0-1-15-aliendalvik-stop-working-and-doesnt-start-solved-removing-android-data/4635

If “theme pack support” is installed it should help.

I have an Xperia Dual Sim. I have successfully upgraded and the SFOS apps so far appear to work.

All Android apps fail … The service is running (I stopped and restarted it).

Am I alone?
Any suggestions?.

At the moment I only have 1 Android app that I use regularly - MusicCast from Yamaha).
