I have a weekly recurring task that I no longer need. I have completed the due date, removed the repeat function, archived, AND deleted it... but it keeps coming back each week. How can I get rid of it??
Sounds like you might be deleting/archiving the repeated card rather than the original.
If you just wish to stop a certain card from repeating, open any of the repeated cards, and scrolling down to the Activity. You'll see a line that says something like "Carlyn copied this card from name of original card". Click on the name of the original card to open it. From there you should be able to stop the repeat or delete the card entirely.
