Chrome uploads prevented by BlockThirdPartyCookies registry key
Posting here as i think the recent upload issues in chrome may relate to this registry key BlockThirdPartyCookies which prevents the uploads to complete.
I discovered at work that this recently has beend added part of Windows GPO changes, having manually removed this made uploads working again.
As far I know chrome is possibly moving towards enabling this by default in future.
Can you please look into this for any temporary workarounds (does h5p require the cookie for the upload?!) and any possibly fix?
The file you are trying to upload might be too large.
