Hi!
I have the same problem, but this trigger doesn't work only when choose a template. If I choose "create from blank" - trigger opens and I can choose suitable form.
Unfortunately, I have more serious problem - there is no dinamic content available for my forms, except "Response ID".
Also flows are working unstable - I get flow action after an hour or more, or even don't get it at all.
Have no ideas, what to do and how it may be fixed...
