In the blog “New in Universal (dec 2020): More process flows actions, install as PWA, form column settings and more improvements” Erik mentioned “The form in task and report popups listens to the SF setting for Number of cols in form”.
Looks like we’re experiencing some sort of bug, because using Universal 1.8 we only get all the fields in 1 column….
Changing the setting to 2 gives an expected result in the Windows GUI, but Universal keeps using only 1 column…
When the number is set to 2 it looks like the form starts with 2 columns and then switches back to 1 column (in a split second).
I've tested this situation (and experienced the problem) using Edge and Chrome.
