Silly me, fell for another bait-and-switch!
Don't know why I would've thought it might actually be possible to "USE" or perhaps "SPEND" my monthly credits that I paid for, NOT SO FAST!! If you generate a handful (20-40) images at THEIR DEFAULT 1024x1024px in any given month, as any normal person/user would naturally and obviously do, you get trapped in PURGATORY, UNABLE TO SPEND ANY OF YOUR REMAINING "1594" credits without paying them more money. Their web-app "magically" (Planned-obsolecencely) shuts-down, refuses to generate ANYthing, and legit won't work anymore if you don't decide to "BUY MORE CREDITS".

Kthx, but first, I'd REALLY LIKE to be able to USE and/or spend any of the remaining ~1600 credits I HAVE ALREADY PAID FOR!!

I TRIED VERSION 1.1, I TRIED VERSION 2.0 & 3. I TRIED EVERYTHING, different browser, reboot, etc etc. NOTHING WORKS. THIS IS A BUNCH OF CRAP!! TOTAL SCAM!!! Kindly please advise via comment reply right here once this feature, ahhemn, I mean "bug" is fixed. I just now reported it via your inbuilt "bug reporting" tool. Thank you kindly in advance for your forthcoming response and correction of your broken web-app.
