@PVE I'll take a look into your problem and try to reproduce it. In the meanwhile, if you can send your logs it would be great.
Here's what you need you to do:
1. Reproduce the issue (and remember the exact time when it happened).
2. Disable "DNS Privacy"
3. Open the app, tap "Send Feedback", select "Contact Support"
3. The mail app will be opened, change the recipient to firstname.lastname@example.org (!)
4. Mention this issue number in the email text
