Hi All,
I am on Linux and my distribution currently is on Chromium Version 143.0.7499.169 (Official Build) Arch Linux (64-bit). In this version the WebSerial is not working (might be related to Chromium) and thus non of the web serial applications work (flasher, console, app).
Now I installed Version 145.0.7582.1 (Official Build) canary (64-bit) on Arch Linux.
I confirmed that the web flasher, the web configuration tool for the repeater and the web app (connected through the experimental USB mode) work.
Just in case you already implemented the permissions configuration from the MeshCore FAQ and it still does not work, the Chromium bug might be the reason.
Best regards,
Falk
