I have connected my ICal and Google calendar to Todoist but the calendar on my IPad itself seems not to receive relevant Todoist dates. How do I send relevant dates to the IPad calendar that appear on my desktop ICal and Google Calendars?
Please clarify - have you connected Todoist's iCal feed to each calendar you use or only to one calendar and then connected this one calendar to another calendars?
You must use Todoist's iCal feed with each calendar you want to sync it with otherwise the other calendars will not carry our feed when you sync them with each other.
Also, please note that Google only updates their calendars once a day so any change you make in Todoist will be reflected after 24 hours on Google even though it will update right away on other calendars.
