Set Monday as the first day of the week.
Open the weekly calendar view.
Expected behavior: the week starts on Monday.
Actual behavior: the week starts on Sunday.

I came to post the same issue.
macOS Sequoia v15.7.7
Obsidian v1.12.7
Tasknotes v4.11.0

This is a recent regression.

UPDATE: TaskNotes v4.11.1 seems to have fixed this: setting the "week starts on" to a different day then choosing Monday again, it seems to stick.

I can report I have the same issue and it does not seem to be resolved with the latest release as I downloaded the plugin just yesterday. I tried your workaround, but still - no matter which day I select, followed by selecting Monday - I get Sunday as the starting day on the weekly calendar.

I also have this problem. (Edit: Interesting tidbit, mini calendar appears as intended.)

Here's what I presume to be the setting's JSON object looks like for me:

    "customDayCount": 3,
