Edits made in LR on other devices not showing in previews on iPhone

I use LRC on my Mac desktop, LR on my laptop (Macbook Air); LR on my iPad (Gen. 5), and LR on my iPhone (16 pro).  I also occasionally use and make edits in LR web.

Edits that I make in LRC, show in the grid previews on all other devices except my iPhone.  If I view a slideshow on my laptop, iPad or on the web, all photos display with the most current edits.  When I view a slideshow on my iPhone, it does not show the current edits (it doesn't seem to show any edits from LRC).

All versions of LR are the most currect, and all iOS and OS are current.  Also, when I import RAW photos from my iPhone to LR, I use most compatible (and not Apple's proprietary HEIF).  I also do not have any HDR photos, nor do I use HDR to edit.
