I also struggled getting into a development ready state due to the readme inconsistencies. An unfortunate barrier to entry.
That said, it looks like this would bring Clickable deps up to date for Noble (once merged):

OP N10 in US on AT&T MVNO. VoLTE working very nicely.
Setting context to dual protocol, I can also confirm 5G works on NSA towers! Getting 90-120mbps download, with no VoLTE issues (still able to send/receive calls with NR data channel).

Let me know if I can be of any help. Trying to get started with contributions, but am just starting out and have only just begun looking through repos.
@standupmobile Thank you!!
Set to 3G with wifi on, rebooted...and I now receive notifications!
I then asked someone to send me an SMS...AND YES! I can now send and receive SMS!
Would like to have LTE...but I am fine with 3G and wifi 100%. Love it! Thanks for finding that. Now I can stick with UT for good! You will see me on the OpenStore soon

I miss having Ubuntu on my phone, and am interested in seeing where we are with VOLTE support?
Unfortunately I had to revert back to Android until support is added.
I may not be of much help, but if anyone would like to point out where I can try to help, I would love to at least try.

@dobey I figured it wouldn't have a negative effect, but thanks for the clarification on which branch is currently being used!
@standupmobile interesting that you point all of that out.
On OTA16, I forced 3G because I was having issues with 4G...and at that time I had no major issues with consistent SMS. Now I am on solid 4G running OTA17...and can only send....not receive SMS.
As for push notifications...it is odd that you found you had better luck with push notifications on 3G, but not on 4G or even wifi. If I wasnt using my pixel 3a as my DD, and didnt want to risk mucking up my APN and losing 4G...I would totally force 3G to see if push notifications work.
I have been looking through the repos as of late...but have had no major findings that could cause the connectivity check to fail on 4G & wifi, but not 3G.
I did notice the move from TLSv1 to TLS1_2 in this commit, but the connectivity check endpoint is http, not https...so wouldnt think it would matter.

@flohack will do, thanks Florian!

@flohack I do not see that message.
