The following worked fine for me: open the Contacts App, select the Contacts wanted, click Share and the Folder wanted with the File Manager App.
This generate a vcf file that you can read, amend, import back in the Contacts App or almost anywhere else :)

Just an extra 2p, Alan Pope BUDS still works fine i believe in case: https://github.com/popey/buds
and finally found back that one at the bottom: https://github.com/mutse/ubuntu-touch-shell :)

2 extra cents here: while trying Convergence over wireless again the other days with a Pro5 and a FP2, i noticed that both phones see eachothers in the Display section!
It is not working though it states Connected when trying fyi, not sure if it could be that opening a port or starting a missing process can make it work...

@advocatux Updated: Pro5/turbo: (64Gb version UbPorts OTA-3): 496M (32Gb version Canonical OTA-15): 679M

@matteo Try with sudo, just confirmed on FP2.

@matteo Maybe nmcli can provide you further clues, try commands like:
nmcli connection show
nmcli connection reload

Hi @matteo

After reboot, do you see "FASTWEB-1-AB8961" in the Previous Networks?

Just made a quick test, removing a file from /etc/NetworkManager/system-connections and after Reboot, the matching AP disappeared from the Previous Networks on mine.

Also, check the content of the file, it carries your wireless details.

So it would look like either your NetworkManager is reading files from somewhere else but still store it there... not sure how to help/investigate more on my end.

About my comment on Pro5, i travel a lot for my job and unfortunately not able to rely on the Pro5 to get a strong 4G signal, even sometimes simply to make calls.
I have now switched to a Fairphone2 for data/phone calls, but still use my Pro5 connected via Hotspot for GPS and other activities.

Hope that helps,
Tera

@matteo Duknow ab the GPS side but the Wifi connections are apparently stored in files at /etc/NetworkManager/system-connections/<AP Name>

Check if this accessible and writable:
drwxr-xr-x 2 root root 4096 May 27 16:36 system-connections

It looks like mounted to userdata somehow:
phablet@ubuntu-phablet:/etc/NetworkManager/system-connections$ df -h .
Filesystem Size Used Avail Use% Mounted on
/dev/disk/by-partlabel/userdata 54G 32G 22G 59% /etc/NetworkManager/system-connections

I have to agree with @ublublu, it is hardly impossible to tell if it "performs" better or not, i managed to run close to 2 days without charging this week which had not happen for a while.
But also experienced multiple reboots with the motherboard getting very hot as previoulsy (when browsing or high wireless traffic apparently)

Just a note, the FP2 mobile baseband update was from "4437.1-FP2-0-07" to "4437.1-FP2-0-08" in my case, stable with no observation on that end so far
