We just upgraded to v9 of Dynamics 365.
Now the "Find availably" functionality seems to be broken, when we use it to find availably of resources it "hangs" with a spinning icon.
Any idea what could cause this error?
I had issues with the upgrade with some customers as well.
Easiest and best way is probably to contact Microsoft Support because there could be some many reasons and there are lots of dependencies.
(e.g. Workflows, or Action not running or updated, web resources that were not updated during update, because customizations were done before)
