What's Wrong?

Both daily and weekly usage session
counters reset unexpectedly mid-cycle
during active use.

Before reset (~2hrs ago): 5h:83%(3h22m) |
wk:84%(2d3h)
After reset (~1hr ago): 5h:22%(4h0m) |
wk:2%(6d23h)

• Daily session: reset during active use

without reaching the natural rollover time

• Weekly session: should renew every

Sunday, but a new cycle started on Friday,
February 27th

• Weekly timer jumped from "2d3h

remaining" to "6d23h remaining",
confirming the cycle restarted mid-week

• No user action triggered the reset — it

happened during a continuous working
session

What Should Happen?

• Daily session should reset once per day

at a consistent, predictable time

• Weekly session should reset every

Sunday, maintaining a Sun-to-Sat cycle

• Session counters should not reset

mid-cycle without user action
