RC2→RC3 worked fine on all my 7 instances except for the test instance. That test server had the “radio” app installed. After updating, I had a weird “menu like” screen, nothing usable. occ was unfunctional, so I manually moved app directories aside. When I hit “radio”, all was back to normal. So I re-moved back everything to its place except radio, deactivated radio in /settings/apps, reinstalled it – and was fine. Strange though. Had this kind of glitch with 18.x and rainloop before, and with other apps, too. What are steps to collect usable debug data in such case?
