SSRS Report blank display



We have an issue to display ssrs reports on android tvbox
if we only display ssrs reports in a campaign, display is always operationnal.
but if we add other layout (video or meteo widget for example) in the campaign, we have some time a full blank display on ssrs reports instead of the good display.
we use the webpage type in the ssrs layout
our goal is to have many layouts in a same campaign (image - video - ssrs reports - meteo widget)

do you ever encounter this issue ?

can we plan two separate campaigns in a row?
ex: campaign 1 : image - video - widget and campaign 2 : ssrs report
display : campaign 1 then campaign 2 then campaign 1 then campaign 2, etc
