I've a problem that I can not fix.
My application is always running background. Billing manager is in Starter Service.
If I call manager.GetOwnedProducts while Google Play Store stopped (self-update or change device language etc.), my application crashes.
I find a same error here...
I am offering an app with an "In-App" monthly subscription, but also with a free 14 day trial period.
(I specified this trial period in my Google play console when creating the in-app subscription).
After some experimentation, I am still not certain how the Playstore handles the trial period...
