Hi guys,
I have the answer from the katalon support:
“The development team has informed me that this issue will be included in Katalon version 8.6.1, which is our next release.ETA is around mid - end of May.”
But I reported only waitForElementNotPresent, but I think if they will repair this bug, it will also fix other issue with waits commands.
Have a nice day and thanks for your help.
Petr
