Can't Receive/Answer Phone Calls

    I have Google Fi. Before this 11 update, everything worked fine. I could make and receive calls. Voice over wifi and LTE worked. Now I can make outbound calls but I can't answer phone calls. When I try and answer, the app just freezes and goes back to the screen telling me to answer or decline. I've even tried different phone apps, turning off wifi calls, restarted my phone, reset network settings.

    How do I revert to the old version?

    UPDATE: I just restarted into safe mode and calls were able to be answered. Im going to try and see if restarting after that works

    UPDATE 2: Restarting doesn't solve the issue after safe mode. I think there's a way to clear cache or something in recovery mode so Ill try that next

    UPDATE 3: Going into recovery mode and clearing cache didn't fix it. I think Im going to have to go with a factory reset

    I am having a similar problem but in reverse. I have an unlocked Tmo Version of the OnePlus 7T Pro Mclaren and I cannot make outgoing calls. (This is still on Android 10)

    The only work around I have found is to switch my cellular network to 2G only.

    NOTE: I previously had an international version of this same phone and never had this issue.

    One thing I noticed was in Safe Mode, where every thing works, VoLTE was turned off and it only went through VoWiFi. Currently to turn off VoLTE is to go into the SIM settings and toggle it off there, but every time I do that, navigate out and back again, the setting is back on. I can't seem to actually turn off VoLTE

    I just did a factory reset and now calls work. As expected the VoLTE is gone and calls are received just fine.

    The VoLTE switch needs to be fixed or provide some feedback to why it can't be switched off.

    UPDATE: After installing the Google Fi App, it switched VoLTE back on.... this broke it again.

    I manually changed my APN to Google Fi to Project Fi (They were listed and selectable) and I manually set my network to google and that solved my issue (So far)

    That appears to have worked.... I will have to test it and make sure it stays stable.

    Is the DNS issue because it is routing calls through the LTE Data?
