We are currently updating our on premise environments to CRM 2016 (w/ update .01) and are no longer able to use SSRS reports, both custom and built in.
When the report viewer page loads, the controls are disabled and the console throws 'Sys' undefined javascript errors. No reports will render.
The issue seems identical to the one listed here, https://blogs.msdn.microsoft.com/arpita/2012/07/20/microsoft-dynamics-crm-2011-unable-to-run-any-reports-due-to-missing-security-role-in-default-organization/ but the advised solutions do not work for us.
We have made sure the users have permissions in the default org, checked SPNs, removed any disabled orgs, re-imported and re-updated orgs (one took a hefty 12 hours to import for some reason), un-installed and re-installed the SSRS Data Connector, and I'm sure many more things.
The environment we are having the issue on is a load balanced pair. We first ran the update on a standalone server, and reports work fine. The setup process was identical.
If anyone has any more suggestions to resolve the issue, please advise.
