Sorry to hear that you’re experiencing this issue.
I’m experiencing the same thing for more than a month now. I submitted a ticket but the response I’ve gotten is that they could not replicate the error on their end and advised me to try logging in with a different internet connection and different computer, say at a local library for example. Hmm…
I agree that the Web Previewer saves up a lot of time as compared to testing it on the app.
Do you have the icon “Story Modifiers”? I really hope you do. It’s the icon in between the icons, “Directing Helper” and “Navigation”. When you click on “Story Modifiers”, you’ll see “Flags”, “Counters” and “Character Points”. I’ve been using “Flags” to test the ifs/elifs/else on the Web Previewer. It helps a lot, especially if you have a fair bit of branching.
The reason why I ask is because it seems that not everyone have the same type of Web Previewer. I posted about the missing “Hide debug elements of HUD” in my insta story before and gotten some feedback from some authors. For my case, my “Hide debug elements of HUD” has been missing from my Web Previewer since Dec 2017 and some people feedback saying that theirs went missing too, some still have theirs, while some did not even have that at all ever since they started using the Web Previewer, which is very odd.
I’ve submitted a ticket. I’ve gotten the same response to try logging in on a different computer with a different internet connection, like the local library for example. I’m upset with the response I’ve gotten as I record sneak peeks for trailers for my stories and I’ve been using the same computer when the Web Previewer got out and manage to record stuff before Dec 2017. I’ve given up recording using the app as it crashes/freezes mid scene and skipped past a few animations when I try to record on my phone and overlays are all over the place on my Android.
Sorry for the rant.
I really hope the Enable Picker thing gets resolved soon. “Story Modifiers >> Flags” is a good alternative for now. Best of luck!
