Couple of things to update you on regarding this issue:
-
Fresh install of Joplin v3.1.17, same OS - Ubuntu 24.10 - no plugins other than Time Slip, everything worked as expected
-
When the plugin is using postMessage for iframe communications, there is no note being returned, eg. for updateLogNotes:
{
"message": {
"name": "updateLogNotes",
"notes": []
}
}
