Today I realized that a flow of mine to simple share a new post via the Facebook app quit working.
It looks like the app stopped responding to control UI.
The flow used to work up until yesterday, when the Facebook app was updated.
I made several tries, incremented sleeping times between commands, restarted the phone, no way.
I cannot even downgrade the app via sideloading, for the Facebook app on the Note 10 is a system app

I tried rebuilding the flow, maybe, I thought, some UI elements changed name, no joy, and, as a matter of fact, names are the same as before.
I tried with another cell phone of mine with Android 8, where unfortunately the FB app was updated, it doesn't work on that either.
I am including the flow.
Any hint?
Thank you.
