The suggested solution from 2021 was incorrect. That option never has had any effect on the “Is this the next scheduled…” pop up.
Unfortunately there is no known solution.
Again, the option to “Decline all suggested reminders” will not stop the Is this the next scheduled…” pop up. Any posts that say the option is a solution are just plain wrong.
