Unable to start account, so I can’t really use the app – Assemblr Studio: Easy AR Maker Review

This app looks like it has potential, but it REQUIRES you to sign up for an account in order to be able to save your work, and when I tried to sign up for the account, it locked into a screen which said “checking username.” It stayed in this state for 25 minutes and I finally gave up. I tried to go to their website to seek assistance, but their “contact us” form seems to be only an advertisement for a “contact form” service online. I was completely unable to get any assistance whatsoever. Would be nice to actually try using the app, but I can’t establish an account, so I guess that’s just not possible. (Incidentally, aside from the developer’s apparent desire to keep exact tabs on whatever a user creates with this app, there’s ABSOLUTELY no reason to require an account of any sort to use this app locally on my device. But hey, apparently I’m a revenue stream, not an actual customer, so whatever.)
