Hi @MikeErh,
There are two solutions to disable "DOWNLOAD MICROSOFT EDGE MOBILE APP" POP-UP. The first one is that you can use Python code to block it. The key code statements are as follows:
options = webdriver.EdgeOptions()
options.add_argument("--disable-features=msEdgeEnableNurturingFramework")
options.add_experimental_option("prefs", {"user_experience_metrics": {"personalization_data_consent_enabled": True}})
The second option is that you can block "DOWNLOAD MICROSOFT EDGE Mobile App" POP-Up by disabling "ShowRecommendationsEnabled" Policy. You can refer to this link: https://learn.microsoft.com/en-us/deployedge/microsoft-edge-policies#showrecommendationsenabled.
