I just tried installing then running the latest beta 2019.1.27.0 but i get an authentication popup window which ive never had before but it then gives me script errors on a js file at https://login.devolutions.com and i cant use my Devolutions online drive data source nor login with my cloud account. I had to uninstall and install the latest RTM version to be able to use RDM again.
