Reporting a bug? This helps
- Your iOS version — Settings → General → About.
- Your Ksefly version — in the app’s Settings, under "About".
- The screen it happened on — "issuing an invoice", "the purchase list", "signing in".
- What happened, and what you expected — step by step, if you can reproduce it.
- A screenshot or a recording — if you can, with anything you would rather not send us covered up.
Never send us your KSeF token or any other credential. We will never ask for one.
