carrier: TMobile, tmobile_us-40000000018.7 (unable to select APN
I am experiencing inability to have mobile data, using these settings:
- Always-on VPN = (off)
- "Block connections without VPN" = (off / greyed out)
From another thread (pertaining to P7 experimental build), the lockdown mode issue with VPN on IPv6 carriers is acknowledged in this way:
strcat There's a known compatibility issue on Android 13 between the improved VPN lockdown mode and mobile data with certain IPv6-only carrier configurations. Try changing your APN configuration from IPv6 to IPv4/IPv6.
My VPN works on wifi, but not over mobile data, with no "lockdown mode" configured.
Is this the same known, upstream issue? Or do I have a separate/different issue?
