PPVS per area won't save

I’m not sure if this is a known issue or just a problem for me.

I turned off “Global Apply” in PPVS and went to one of my roadside areas and tried to change the settings for that area. When I hit the check/save button I just get a loading spinner hanging forever. The only way out is to force quit the app and open it again.

I am running on iOS, latest app version, latest firmware (3.18.6 app / 3.13.14 fw).

I tried rebooting the core, I toggled the PPVS on and off, I toggle global on and off. No combo seems to make a difference, always get stuck saving.

Thanks for any help.
