Sudden 403 Forbidden Errors on /timeline/fetch endpoint, App has Analytics permission

In this case, you should submit a developer support ticket. It could be something changed in your credentials.

Thank you PhongVu. I submitted a ticket earlier this morning and am now waiting to hear back.

Just to let you know that I see an internal escalation. It seems the issue relates to the new release which causes the problem. They will release a fix soon today so please don’t try to fix your code but stay tuned.
