I have just upgraded from 10.2.100 to 10.2.700.24, we have an updatable cross company dashboard that previously worked fine but after the upgrade only security managers can save a record in a company that is not the native company of the query. All other users click save, get no error but upon refreshing find that the record was not saved.
I have tried increasing the Query timeout with no change, the regular user has access to the all companies involved and security managers can use it without issue.
