I’m very sorry to hear you had such a poor experience as well. I’m sure it’s little consolation at this point having been inconvenienced as you have — it’s certainly not what I aim for in my work!
Thanks. I did test your new version but unfortunately similar issues. App completely hung and entire OS was sluggish. iPhone 13 Pro, iOS 17.1.2. Unfortunately I won’t have time to test any more but very good luck with the project.
