I have exactly the same issue. That sucks
Same here. I installed app version 3.1.37 this morning and thought that had fixed it as previously saved scenes showed up but now when I look they have disappeared again. Plus bulbs are still unresponsive in Alexa.
After some more testing, it seems that this has only partially solved the problem. The issue still persists in Alexa (I can only see my scenes, no devices).
