Sharing powerpoint slides with individual windows doesn' work

Hi, I’m not a developer. I can’t find a ZOOM users forum to ask this question.
I’m sharing a powerpoint presentation from my laptop. I would like to choose “Browse by Individual Window” under setup slideshow -> show type. But, now people connected to the meeting by phone do not see the powerpoint slides advance. They are just stuck on the 1st page of the presentation even though I’m advancing the slides on my laptop. WhenI switch setup slideshow -> showtype to “presented by a speaker (full screen)” this behavior stops. When my presentation is on full screen it advances and behaves fine on the phones. Does anyone know a workaround? Thank you for any help.
