Currently, if you stream from a console (PS4, XBOX One or Nintendo Switch), you cannot use Streamloots alerts or alerts from any other platform.
This is due to a technical shortcoming of the software used internally by these consoles to relay the video stream.
However, yes you can use Streamloots on your PS4, XBOX 360 and NINTENDO SWITCH , but it must be through a video capture card.
From Streamloots we can not support this type of configuration because there are many brands and models of capture cards, and each one is used in a different way.
If this is your case, we recommend that you look for information on how to insert browser sources in your capture card, by typing brand and model in Google.
This way, you will be able to insert streamloots alerts into your stream with a video capture card.
