I’m also having this issue. Tried the steps above as others have and had no luck.
After HOURS of trial and error, I switched to the Classic app and it worked (and showed up on the new app as well).
As someone new to ST, I have to say that having two very different and not completely consistent apps is a Royal PITA!! I’m now sort of used to the new app, so the Classic looks odd to me, but I’m sure that’s all about what you’re used to. But now I worry about what will happen when the Classic app is deprecated completely (not to mention the demise of the IDE). My inclination is to do as little as possible until then to minimize transition issues and hope like hell that the API approach is more intuitive than the current system.
Anyways, thanks for the clue to try the Classic app!!
