Describe the bug

After fiddling around with #285 I finally could enable the WebUI.

Upon connecting to it, I see no public channels except of Public. But on device, I had several channels, and not Public.

Also, I see only one contact, although on device I had many contacts.

Now, going back to device, I see that all my channels and contacts are gone.

Could this be related to #271?

I restored (seemingly successfully) from backup.

Then tried WebUI again. Contacts and channels were not deleted that time.

Then did this test. After some time, something has crashed: Device was not ping-able anymore. After restarting WiFi and reconnecting to WebUI, contacts and channels were gone once again. And reappeared shortly after.

Which device are you using

LilyGO T-Deck Plus

Which Firmware are you using

v0.9.12.3

Maybe it's not directly the WebUI but some other stuff going on, just incidentally beeing triggered by WebUI? https://github.com/dabeani/meshcoreterm/issues/306#issuecomment-4614479661.

The severe version here (contacts actually gone, needed a restore) matches #271/#332/#333, which had two confirmed root causes fixed in v0.9.14 (an NVS key-length bug, and repeater login rewriting the whole contact store). The milder version you saw later — empty, then reappearing after WiFi/WebUI reconnect — looks like a display race at boot (WebUI can answer before contacts finish loading from SD) rather than real data loss; nothing writes an empty contact list to disk just from that. The actual crash during the #201 stress test is the open thread — if you can reproduce it, a serial log from the point it goes unresponsive would let us root-cause that specifically.

I won't use the WebUI anymore due to my bad experiences with it & it was only for playing around since I want to use the device standalone. So I do not test if this (#286) is resolved. I just assume "yes".

I also won't do a test for #201 for the same reason.

So, closing.
