In settings I have set my Start Page to a project but when I access my lists the preference is not loading.
Please tell me - is the project you've selected still active? Have you deleted and recreated it in the meantime?
If not, does it have any special characters in its name or an asterisk * at the front (making it a category)?
Yes the project is very much active - has 110 entries
no special characters
Please try to set a different project as your default and let us know if the issue persist and then if setting the other one again still won't work.
Also, please make sure that if you're using a bookmark to access Todoist, it links directly to https://todoist.com and not any other URL.
followed your guidance and it looks like the url was incorrect. The default project is now loading up fine.
