Viewers Not Seeing What I See as Host

I am hosting a hybrid meeting where I use two cameras, each focussed on half of the group of 10-12 who attend the meeting "live". The view I see on my screen shows the views from both cameras on site plus the 8-10 participants who are attending virtually.  Some virtual participants who use phones or iPads cannot see both cameras--- which is a limitation I can do nothing about. But others on other kinds of laptops cannot "see what I see" and claim to only be able to see one camera. What can I do?
