We have migrated from SQL 2008/SSRS 2008 to SQL 2017/SSRS 2017. We still have one issue where I cannot see the subscriptions I created in 2008. Below is the error I get.
I have my domain account setup as System Administrator/System User in Site Settings and I am in an AD group that has Browser, Content Manager, My Reports, Publisher, Report Builder to all folders/objects.
I have googled & googled and all articles point to this being a SECURITY issue, but I cannot see what I am missing.
