Hello,

I have the same issue that some time ago lukass2000

But the daily limit begin to run from the first login.

If I allow 4 hours a day.(Daily Limit / Sitzungsdauer 4 hours). When I log in at 8 o'clock, the 4 hours expire at 12 o'clock. Even if I was only online from 8am to 8:30am.
It is not remembered that half an hour of the 4 hours is used up.  So there are still 3.5 hours available for online.

For the daily time frame I found the setting, that works too.
