Thank you for the detailed description of the issue and the demo. It occurs in cases if the event has the same(or exceed) end time, as the last_hour config. I already sent it to the dev team, and they will work on a fix.
The support is now over. This means I will have to revert back to v6 ? I won’t have the fix for v7 ?
Yes, if you don’t have active license - you won’t receive bug fix/minor/major updates. But you can prolongate your license any moment by contacting our sales department.
