When using RD Client on a Samsung Galaxy Tab S8 with the official keyboard case, when clicking the "cmd" key on the keyboard (akin to the Windows key), it takes me to the assistant instead of capturing it within the RD Client app.
This behavior does not occur while in Dex mode. This behavior also does not occur when using 3rd party remote desktop applications like Remote Desktop Manager by Devolutions.
This behavior has persisted for years as it was the primary reason I switched away from my Tab S6 to my iPad.
Also within Dex or normal Android mode, two-finger tapping on the touchpad does not right click, instead you must right click with a 3 finger tap instead.
