D855 Rom AICP 10 release ver. Issues

I have installed AICP Rom on my D855 and have found the following issues. Anyone else notice this if so how can I fix it.
- does not save my WiFi connections, has no option to save connection either Its annoying putting the password in all the time
- My signal strength is terrible. I can get service in my house anymore. Happened straight after changing ROM.
I am running stable release version on AICP 10.0 has this been fixed in any nightlies?
Should I use a different ROM. Tell me if you have had the same experience.

Volte loosing issue in oreo roms

i have tried each and every oreo rom available for lenovo p2 and using jio roaming
i am facing volte loosing issue after certain reboots in every rom,
i tried swapping sim cards, flashing stock rom using fastboot and did all the ota updates, tried adding ims to apn type, adding some build prop lines and also tried vreating new apn ! still no success
not facing same issue in los by code elixir but dont want to use it as it has less customizations.
any other solution available for this problem ?
i know most of the developers dont use volte so dont care much about volte but most of the indians are using Jio som cards for calling and internet accessing purpose
So devs i humbly request you to find solution for this issue...
Ya its a big issue in using Oreo rom. I am back to Lineage os 14.1 .
Flash the modem of the stock ROM when you lose the connectivity. It worked for me.

VoLTE is a PIA for developer's. not just because the code is proprietary (meaning no access to the source code).
the Dev's so far have not focused to fix VoLTE for Oreo hence the issues. they focus on other major more important fixes first.
Oreo is a major re-write to C++ compared to Nougat.
VoLTE on 14.1 is stable because the Dev's have figured out a proper way to make it work. Which is not yet the case with Oreo. so if you want stable VoLTE stick with Official LOS 14.1.

How to flash stock modem .
I am on AEX.
---------- Post added at 07:50 AM ---------- Previous post was at 07:46 AM ----------
I think AOSP roms have volte problems.
When I am on AOKP os volte working fine..
Yesterday I flashed AEX which is based on AOSP.
Volte gone.
One way to get back the volte is by changing the sim card from 1 to 2 or vice versa. This will get you volte. And then if you want to change the sim cards back to original then do so. The volte will stick.
Other one is, flash the stock ROM modem or an LOS modem. It worked for me with stock and RR modem.
