We have two work station with seperate licenses and we get this problem on both computers.
When you customize Adobe Acrobat Pro DC 32bit tool panel, the tool panel stays customised only for short while then goes back to default. I cannot wrap my head around this and it is driving me crazy having to set it up every day; some times more than once.
If i customise my toolbar now, it will stay customised even if i close the application; but randomly through out the day it reverts to default. I cannot see a pattern in my workflow causing the occurance.
Below is screenshots of my PC specs, Operating system as well as adobe version.
