Has your Wemo Light Switch Long Press stopped working?

My Wemo Light Switches have recently stopped reacting to “long press”. The switch itself just does not seem to want to do it. I’m wondering if this came along with a recent software or firmware update, because previously, this worked very well and was very useful alongside Home Assistant.

(To be clear, I don’t think this is a home assistant longpress event detection issue – this seems to be a recent regression/issue with the hardware itself, and I’m wondering if anyone else is experiencing it.)
