I've used the app with no apparent problems on one self-hosted Taiga instance, on one project, for free. As soon as I paid for the premium (one month) after operating briefly, the app never starts; it looks like it's starting, and crashes before displaying any screen.
It is now completely unusable, yet paid for.
I run an iPhone 11, the latest iOS (13.3). I have tried to close the app, starting it again from scratch, with no improvement.
Please tell me what else I can do to help debug the issue?
