I tried today on Chrome browser and have the same issues.
Here’s how I started off, 4 commits ready to be installed on the docker_manager
Then when they’ve finished and I come back to the Versions tab, it says last updated 13hrs ago for some reason but the upgrade button is still clickable (I’ve not dared click on it again!)
If I CTRL+F5 to refresh my browser then it changes to “Up to date”:
I then install the 75x commits for Discourse.
When finished, I click on the Versions link again:
And the blue Upgrade button is still clickable:
Again, a CTRL+F5 refresh sorts it out.
This time I used Chrome v81.0.x on Windows PC.
It never used to do this, but it has been doing it for months now, I just forget how many months
