As a pro-brewer and one paying for the pro level. It would be nice to have a ticket based support for bug reports. It is too easy to get ignored in a forum.
Resurrecting this old thread. I'm having the same issue. I'm trying to delete an empty folder from my cloud files but it crashes Beersmith 3 (3.2.7) every time.
EDIT: I was just able to delete it by accessing my cloud files in the Beersmith app (iPhone). All is well again.
