Switch to another theme?
Switched to another page builder?
Switch apps again?
How can I switch back to my old theme?
Switch back to your old theme, use the switch to switch back, switch back again, or switch back and forth to another one of those themes.
For example, to switch to a Google Calendar page builder like My Calendar, you could switch to the Google Calendar Page Builder app and then go to My Calendar.
Then switch back.
Or you could use the Switch to switch Back to Calendar app to switch your calendar back.
