whenever we make a change (update) in MWS partner profile, change won’t reflect the same after some time or days. Every time we had to delete the existing configuration (external id / preferred protocol), save it. Then add new change and save. (direct update on existing external id / delivery setting / preferred protocol is not working)
we are using one MWS (http://Mws01:8585/services/SAML) connected to one data source (one database) in mws and 2 TN A&B servers are configured in mws.
Imo it is not directly related to your issue, but yes. You should configure your MWS cluster(front end) url and saml resolver to be the same. I usually request a load balancer url for this purpose. The MWS LB needs to be configured as sticky session, otherwise the session cookie wont be shared between nodes. As documentation suggests, logging off after changing user data should resolve your real problem.
