Hello,
before i ask for help about specific problem i'll write short review of what happened.
We had CRM 2013 on-premise and i was able to debug workflows with Plugin Registration Tool 2013 (ver. 6.1.1.1143) after upgrade to CRM 365 (Version 1612 (8.2.10.24) (DB 8.2.10.24) on-premises) PRT from SDK 2013 was not able to connect to new version of CRM. So now i can connect to CRM only with PRT from SDK 2015 or newer but then i'm not able to debug workflow anymore.
Problem on PRT 2015 or newer is that steps are not visible when i try to profile workflow.
What are the options?
Thank you
