When using domain name, the app uses the IPv6 address. It would be nice to be able to select either IPv4 or IPv6. It is also very annoying that I always have to switch from UDP to TCP for EVERY entry. When switching from UDP to TCP for one entry, the app jumps down to the latest entry. So if I want to change multiple entries, I always have to scroll back up. Bute besides these issues, the app works fine.

The closed port do no work with the app. The same configuration work on a windows client. Why ?

Using Samsung Dex on Galaxy Fold Z4 Android 14 I could not access the port fields and had to create/import a json config (might be an edge case). Otherwise, great app that works as advertised.
