What up with traditional insurance cancellation times?

I just bought a policy with Coya and wanted to cancel my old insurance policy. The process to cancel wasn’t that difficult but still annoying (had to send a written letter to my insurance company.) When i got back the cancellation confirmation, they said my old insurance will be cancelled in March!!! That’s in 6 months from now!!! Crazy…

Love that Coya has daily cancellation, really hate being tied in to long contracts, especially when I don’t even know about it…
