Since the August 10, 2026 Build 88.00.43-release+20260804.fcdf713 update to the Sonos App the EQ Shortcut on Now Playing Volume controls does not work with Stereo pair One SL or original Sonos Arc.
I have uninstalled/reinstalled the app with no luck.
I have rebooted all Network devices including the WiFi router
I have removed power from all Sonos devices then powered them back up again.
No Luck
