My default time zone was America/Toronto. In trying to select Canada Eastern time zone, which isn't an option btw, I have lost this default time zone and can't find it to reselect?
I live near Toronto Canada, which time zone should I choose? The selections I need aren't there! My iPad is set to Canada Eastern as it should be. Are you expecting the issue with Sunday hiding to be fixed after dst? America/Toronto is not showing to select and I was still having the issue with Sunday hiding anyway!
We're sorry for the inconvenience, this issue should indeed stop once the DST ends. As for the time zone - please always use the time zone Todoist suggests to you if you access it on the web. If you only want to change it because of this issue with the 7 days view - please don't because these tasks have all the correct date and time and if you enter any project, you should see that they're correct, but changing the zone will certainly introduce such issues permanently to your tasks as after DST they will then really change the dates/times.
If you just want to use the time zone to match the area you're in - the name of the zone is basically irrelevant, you can pick any other country or city that's in the same zone as you are.
