I didn't believe this would happen, honestly.
But we did it.
We are back in the Google Play Store with the latest version of Subsurface-mobile. Which of course has way more changes than the release notes panel will allow me to put in. But hopefully people will be happy with it.
Everyone who has sideloaded the app for the last couple of years, you should be able to upgrade to the store version as they use the same keys - but sometimes Android is weird about switching between store apps and sideloaded apps.
Either way, the Play Store integrates with the regular updates, so it may be convenient for some to switch back - but we will of course continue to update the sideload apps as well.
