I did open a case with CS_Agent and it was escalated to a technician with Public Mobile. Sounds like parts of the network have already been redirected to the new proxy address, which caused my phone to stop working. From what the technician can see my Essential Phone PH-1 is not using the new APN I had created and instead is still using the original APN with the old proxy address despite the new one being selected. I cant seem to edit or delete the original APN through the regular settings. I might attempt some other means to make my Essential Phone use the new APN settings, but the issue is with the PH-1 itself.
Correct APN settings should allow MMS to work, but only if your phone will actually use them!
I am running a BlackBerry KeyOne running Android 8.1, and seem to be having similar issues as you... Updated APN settings entered in a new APN entry, but can't delete the old one. I also suspected it was just continuing to use the old settings APN profile that I can't delete.
I did find a workaround (for now) though - if I temporarly switch networks to WCDMA/HSPA instead of HSPA, MMS works fine. (I can test by sending pictures/stickers to myself...). Who knows if this will also fail to work in a few more weeks.
I did also try @RavingRaven's suggestion of temporarly swapping in an old Roam mobility SIM which I happenned to still have, and while the Public Mobile enforced APN entry disappears while that SIM is in the phone, it comes right back as soon as the PM SIM is re-inserted, so that doesn't help...
I know I really should get off this phone as it is indeed a 2017 model that I acquired in 2018, but other than this it still runs great and I was really trying to see how long I could go on this reliable workhorse!
