Thanks for the detailed report, genuinely helpful. Both of those were the tutorial spotlight aiming at the wrong spot and then hard-locking on the Rebecca hack. Just pushed a hotfix for it. Hard-refresh (Ctrl+Shift+R, or Cmd+Shift+R on Mac) to pull the new build and it should walk through cleanly now.
I'll try to figure out a targeted cache dump for my cell's browser. Might just switch to a new browser.
Another heads up - the tutorial forced focus still triggers in the event of a user leaving and returning later. Since the "while you were away" progression notification takes display and interface priority over whatever the tutorial is trying to indicate to, that's another potential hard lock scenario.

First of all, E5Burrito, genuinely thank you so much for your input, it helps a lot. I will push a fix for the tutorial funnelling later today (hopefully the last one). As for the game freezing, I think that is an issue with mobile devices. Currently looking at what I can optimise to make it run smoother, but this one might be trickier
