nostr:npub10r8xl2njyepcw2zwv3a6dyufj4e4ajx86hz6v4ehu4gnpupxxp7stjt2p8 I upgraded 0.1.5 -> 0.1.7 and I had issues with never ending spinner on buttons so couldn't install/update apps. I deleted cache, but nothing changed. Then I deleted all app data and restarted the app. Now I see nothing but the spinner for 20 minutes or so. What can I do to get out of my misery?

Oh, a force stop allowed me to see stuff normally again, but now I'm back to the never ending spinner on the install button. 
Sorry to see that.
On top of it, everyone is seeing spinners right now (for latest releases at least), as there's a blocking query on nostr.band relay that is down today.
A few good news that I hope will solve this for you:
The blocking query bug above is fixed.
A bug causing a stupid amount of unnecessary connections to relays was also fixed.
I want to release that in 0.1.8 asap BUT as we can't see latest release users can't update😐
Thanks for the hints. I got it working again. However...
I uninstalled Fountain, which was installed though another app store, and then went back to zapstore, searched for "fountain" and got hit by this message: 
This looks like a pretty bad error. What do I do?
