Free App Paint not working?

I’ve used Trimble Identity in my classroom a lot. Was just prepping for use this week and it seems that paint no longer works. I click on the paint bucket and it doesn’t do anything (clicking the paint bucket on a surface does nothing). Occasionally the paint bucket turns into the eye dropper (color sampler) and then cannot be turned back into the bucket.

I noticed there was an update on Sept 4 - am I the first to find this bug?

What browser do you use (version)? Maybe updating will solve this.
In Safari, for instance, the cursor does not change in the bucket, but remains the pipet.
On Chrome, it works as expected. I am using Chrome Version 68.0.3440.106 (Officiële build) (64-bits)
