The Network Access Point Mode seems pretty unstable for me in this Beta. Do you already know that? Do you have the same bug? Is there a trick to solve the problem?
The main issue with the hotspot feature is user expectation. ConnMan provides a deliberately simple WiFi hotspot not a wireless access point. It is designed for tethering a laptop to a mobile phone. It was added to the distro by me so I could connect to Hotel WiFi and (via the hotspot) pass the WiFi password check to get the HTPC onto the internet and watch a movie via Plex. It works for that and similarly simple tasks, but it is not a network access point or router - if you want a router, get a router. The second issue is that RPi has a weak antennae which users often hobble further with cases that impair signals.
I'm not sure why the settings add-on would lose the region config .. but this is not used when running the access point (which has an internal harcoded config) and switching between hotspot/wifi modes may drop the setting.
