Wiim pro plus having issue with Wifi7 router

[leejy2]

Have anyone encountered this issue?

a little background,
I recently changed to a wifi 7 router, from a normal gigabit router.

Old router (gigabit router) connect via 2.4Ghz band
App can detect Wiim pro plus
Controls on Wiim works (Volume control buttons on wiim can be pressed and it shows on volume slider on device on the wiim app)
Spotify can see Wiim device
No issue

New router wifi7 TPlink-Aginet HB810 (connected via 2.4Ghz band)
App can detect Wiim pro plus
Control on Wiim works (Volume control buttons on wiim can be pressed and it shows on volume slider on device on the wiim app)
Spotify cannot detect Wiim device

So this is the issue with new router? both are TP link routers
