Help needed - picture library slideshow web part - photos not changing on time period

Question

I'm using sharepoint 2013 for our works teamsite. On the home page I use the web part to display staff photos from a picture library. This has worked in the past fine - updating every 5 seconds. When the page comes up it displays a random photo from the library but it no longer updates the photo after the time period. If navigating away from the page and back again a different photo does display. Settings for the web part are Duration: 5 seconds, Library view - All pictures, display mode - random, Display with: Title and description to right, fixed ht 200, fixed width 300,

I did change which picture library was used sometime back but it worked ok and have reverted to old versions to double check and that no longer works.

I've deleted the web part and recreated. I created a new picture library and copied pictures across in case there was something wrong with the library. I've tried IE, Edge and chrome. Have run out of ideas. Any help would be appreciated.

Well, the feature of Picture Library Slideshow Web Part for automatically doing slideshow based on certain time duration will not be working for your Picture Library until CDN is enabled. Find Reference

So to solve the existing Issue for your app, Please ask your O365 tenant Admin to enable CDN.

Action Plan: Use Powershell commands to enable CDN by following this MS Article
