One of my customers is using a native application that runs on IE6. Since IE has been deprecated, my customer runs it with MS Edge Chromium under IE6 compatibility mode and can run it well as expected. Next, they want to use an RPA solution and one of the requirements is to interact with the application that runs under IE6 compatibility mode (the interaction is to do the web scraping).
So, I tested it using Nintex RPA and found that the web scraping failed to detect the web page (no dotted rectangle appeared). I tested it with another page that is not related to IE6 compatibility mode and it works well (dotted rectangle appeared as described below).

Does anyone have an experience like this? Or could it be a limitation of features from Nintex RPA which could not support IE6 with compatibility mode? Need any input on this.
