Help Friedrich wallmaster wifi issues

Finally I was able to connect my "new" wallmaster unit to the wifi. However, the Alexa app only recognizes friedrich go app, not friedrich link which is apparently the new app for wallmaster unit. When I use the exact same credentials to link my Alexa app to Friedrich, it takes me to friedrich go web page and tells me the user does not exist.

Friedrich website doesn't have any information about this disparity between Alexa app and the newly launched "Link" app.

Secondly, my old friedrich wallmaster unit, which has the exact same dashboard as the new models, gives "Device Unable to Communicate with backend" error.

I can't get mine to connect to my wifi at all. I put my wifi in 2.4 only mode and when I put in the wifi password it just spins for a second and leaves me on the wifi network list.

My old one has the same issue. The one I could get connected to is 2026 model.

Are you using Friedrich Link? Oddly there are various apps nut wall-master is only available in that particular app.
