Mirroring issues with wifi 6 AX1800 WAX204

[JCLUSBY]

I've not been able to get my airbender app or ApowerMirror app to let me screen mirror my iphoneX to my firestick 4K max despite all the suggestions to correct it online.  I was able to use these apps prior to upgrading to the WAX204 router and the new 4K max and now neither of them work nor does the Screen Mirror capability built into the 4K max work   Any suggestions as to what I could do to my wifi router that might fix this?

This is the only router in the system, correct?

When the iPhone and Firestick are connected to WiFi, they both show up on the router connected devices list (page 158 of user manual)

Darn.  The instructions seem pretty simple: https://techwiser.com/mirror-iphone-amazon-fire-tv-stick 

Alas, I have neither product so cannot experiment.

There are many Apple owners on the forum. Maybe one of them will chime in.
