Ring Video Doorbell 2 not working with TP-Link Deco M9 plus

I have a TP-Link Deco M9 plus mesh and just got a couple of Ring indoor cameras. I cannot get it to connect to my wifi network even during setup. I tried everything, reset my router, reset the camera, turning off the 5GHz,… but reading through these posts, it seems like I won’t be able to get them to work.
