Wtf. I was sure i saw my current app version, but no. My main account/phone is on beta program and my actual app version is 1.0.43(2283) and comes with bundled fw 1522204715.
I just installed regular app from play store to factory reseted old phone and got both same versions as you. And there is no trashcan.
You should be able to join beta-program and download “new” 3 years old version, which basically gives you log deletion and working 10 minute logging interval (there was a variable overflow bug which gave little over minute as a maximum)
