Single Pole Smart Light Switch White, Tapo S500(4-Pack)

The switches will not work with my Deco app as they are supposed to. I have to use the Tapo app. When I try to add them to my Deco app, I get the error code that the router firmware is out of date. Both my Deco units are up to date and the switches confirm that they are up to date as well. I'm very frustrated. I giving this three stars because the switches work as manual switches and do work with the Tapo app.
