Android app has no dimmers 

This happened a while ago, and frankly I didn't think it was worth the battle to get help, but thought I'd get it out there.

When I first downloaded the Android app, all worked well for the initial release, at that time, the dimming rings on long-press worked GREAT (still would rather have linear swipe to control the rotary dimmers). A while back I noticed the long-press no longer brought up the dimmer controls. I lived with it a while but now just tried deleting and reloading the app from Google Play, still inop.

Nothing has changed in my devices, and all of them dim if I go through the device list and pull down the number panel for dimming percentages. Also the dimming rings show up and work as designed on long-press from my laptop in any browser.

Phone model is Samsung S7 (non-edge) running latest OS.
