This morning I started getting reminder notifications showing up on my phone/watch. These are all from previously deleted items and clicking on them sends me to my list page. (Interestingly, not to the specific list that the item was on.)
Apologies, we should’ve done a better job turning off that feature and cleaning this up. If anyone is stuck in a place with tons of annoying useless reminders scheduled in the beta chime in here, and we can see if we can set aside some time to clean this up better.
