Error 1355 cannot run subscription with owner being from old domain

We are migrating from Domain A to Domain B, and there is a trust in place.So in Domain B, I can add DomainA\User no problem, and they can continue to run the reports under the existing (old.default) domain.However for any subscription with the owner being a DomainA account, the subscription fails with AuthzInitializeContextFromSid: Win32 error: 1355SSRS is running under a Domain B domain account and for subscriptions created by Domain B accounts, everything is fine.For info: We are moving from SQL 2008R2 (domain A) to SQL 2014 (domain B)It must be an AD setting, I think, Thanks
