Yes it does work. That version is still called Flow, not Power automate, by the way. Shameful how Microsoft can ignore an obvious issue like this. Did you hear Microsoft ? Now I have to go and disable automatic upgrades on the app I just realized... Or not, since I installed side apk... DID YOU HEAR, MICROSOFT, FIX THIS ASAP! IT'S BEEN MONTHS!
PS. 2020/06/18: Since I installed the prior version, my phone updated to version 2.36 which is titled Power Automate. This one version works now, it used to not work before. What happened in between that might have something to do with it is that I uninstalled the Authenticator Android app (Msft), which was causing problems with Microsoft Teams. The issues might be related, who knows?
PS2. 2020/06/18: Even though PowerAutomate works now, it's still not perfect. The button triggers don't work, inside the app, or outside, through the widgets on the home screens. The widgets fail to connect to any of the flows, cannot be created. The button triggers inside the app fail with "try again later". Who on Earth still responds to a failure with "try again later"?
