I have users that have paid for time slots, and it seems the times have moved. One user i know was booked at 5:30pm and the time keeps getting changed to 1:30pm of the same day.
I haven also noticed that the amount paid is being wiped out as well
It looks to be reproducable.
Whenever I save my settings in the “Connections [BETA”] area, the times will change to 4 hours before their original times.
I found that removing the Goggle calendar sync settings and tockens prevents the issue.
there is simple solution to this. Please open WP Settings > General and change time zone to be named time zone instead of time offset. For example Europe\Berlin instead of UTC+1
This was the first item i tried and it did not work. Only removing the Google Calendar syncing seemed to fix the issue.
I will suggest that you remove that appointment on both sides and try again.
