Oontz Angle 3 Pro (Sept 2024) power switch issue

Good day, all. My Oontz worked as expected up until about a month ago when someone else used it.  Now it looks like the power switch has been broken.  When I charge the unit the red light under the power button pulses slowly a few times and then goes steady.  I believe this indicates the speaker is fully charged.

Then when I press the power button nothing changes.  Light stays solid red, no sounds emitted.  I suspect the switch because I cannot feel anything under the rubber switch cover.  All of the other buttons give an audible click when pushed.

Has anyone opened one of these up?  No visible screws so it may be glued closed.

Thanks,

Hugh
