Calendar default view changed somehow, how to restore previous default?

Hi,
on NextCloud 24.0.7, when I visit Calendar’s homepage from a browser
/apps/calendar/
I get redirect to the default calendar view, that it used to be dayGridMonth
/apps/calendar/dayGridMonth/now

somehow this default is changed, now visiting
/apps/calendar/
I get redirected to
/apps/calendar/timeGridDay/now

This is happening only for my NC user, I have checked with a colleague, and he is still on the dayGridMonth default.

It seems that the change happened after accessing calendar from Firefox Android.
Now every time I visit
/apps/calendar/
I get redirected to
/apps/calendar/timeGridDay/now
no matter the browser I use.

If I manually set the url to
/apps/calendar/dayGridMonth/now
this is not persisted.

So how to change Calendar’s default view to dayGridMonth?

It seems that each time you change the view via UI, the new view is saved as the default one.
To set dayGridMonth as the default, just selected it in the GUI.
