Thanks for the quick reply!
1. What browser are you using to render the report? Also have you tried a differant browser?
I was using 'Internet Explorer' (didnt try others) - works with both EDGE and and Chrome!
2. If your using Chrome can you open the developer tools (F12), refresh the report and let me know if you see any errors in the console?
No errors. 2 warnings: "[Deprecation] 'webkitURL' is deprecated. Please use 'URL' instead." & "VM1193:2259 [Deprecation] 'window.webkitStorageInfo' is deprecated. Please use 'navigator.webkitTemporaryStorage' or 'navigator.webkitPersistentStorage' instead."
3. Are there any other visuals on the page besides the Timeline one? If so do they render?
No, just Timeline
