As we have Angular web pages running version 6 and 7 that was released in 2018 they do not work on the version of Chrome that launches with Selenium on Alertsite. When you launch Chrome in alertsite it uses version 49 of Chrome which was released in 2016. Using Dejaclick Chrome launches in version 74.
Suggestion. Upgrade the version of Chrome that Selenium launches in Alertsite to version 74 or greater.
