Sometimes we see Power BI have a blip where a visual won't load, it's just a transitory issue that can be caused by any number of things (network, Power BI, gremlins). A page refresh would fix it on a normal browser, but displagent picks up the error and ceases to function when ideally it should just continue and log the error so if it is a longer term issue with a report it can be identified. Having it stop the slideshow dead means unattended installations need constant babysitting, which isnt ideal.
