I installed Lineage 22.2/MindtheGapps yesterday on my Pixel 3a, but I cannot get Wi-fi calling (or messaging) to work. I can see that VoLTE is available/provisioned. But when I try to toggle the "Wi-Fi calling" option under Verizon it toggles back and says that the "Carrier Setup keeps stopping."
I was running vintage Sargo until yesterday on this phone, and Wi-fi calling worked fine. I live in an area without cell coverage and so I depend on Wi-fi calling, but I haven't found any solutions online.
Any leads? I probably shouldn't go back to Sargo...
Just letting anybody know, if you are reading this, that I have been trying to find a solution for 5 hours and I would now like to scream. My level of ineptitude feels like trying to communicate in another language using only a paper dictionary. I am not a developer and can barely operate the command prompt. I need to go back to stock. Peace be with you.
