We've had an issue going on this year that we haven't been able to figure out. We started trying to use the Photon events in our cloudscript, but were noticing those events weren't firing. We were just using it at the time for extra logging, so we just let it go and moved on.
Later this year, we stood up a new app on playfab to use for dev/testing a major new release of the game and things seemed to work fine for those same photon events. We thought we had fixed the issue through our updates.
When we pushed our new update live this weekend to our production app (C1B3), we are still running into the issue there with photon events not firing correctly. This is causing some erorrs in our script where the script expects a roomID to be present (set via the Photon events).
I did some more searching and found the issue below, is it possible our C1B3 app is in the same state?
