I selected a few plugins on web interface and after that tried to install them in Katalon Studio with Reload plugins option. Some of plugins don’t appear in list, but they are present under my profile. One of these plugins, which are unable to be installed: https://store.katalon.com/product/28/TOTP-Generator-Keywords
It was caused by wrong min and max KS version set for the plugin.
We’re contacting the plugin owners to correct the setting.
Thanks, it is working!
