In SP2013 farm I have 2 User Profile Service Applications (UPSA) running and working fine.
UPSA1 --> Using SharePoint Synchronization >> associate with WebApp1
UPSA2 --> Using ADI >> Associate with WebAPP2
One MySiteWebApp mentioned in both UPSAa in " mnage MySite.
Q1 : Do I need My site web app per UPSA? or can single MySiteWebApp work with multiple UPSAs?
Q2 : If I add an item in column " User or Group" picture shows up for user in WebApp1 , If I add an item in same column in WebApp2 user picture does not show up here. I am using script to download and sync pictures for UPSA2. and its the same mysite that has pictures in " user photos" folder. Any advise why pictures don't show up in WebApp2 using UPSA2 (ADI)
