Error When Moving Ministering Sister Interview Assignments Between Counselors

When my Relief Society president tries to move ministering interview assignments from one Relief Society counselor to another, she gets an error message "Sorry, something went wrong loading the requested data. Try refreshing the page or try again later",

Once, refreshing the page which forced a new login made the change of ministering interview assignments from one counselor to another work. Most other times refreshing the page did nothing and the same error message "Sorry, something went wrong loading the requested data. Try refreshing the page or try again later" message kept appearing.

Is it on Sundays that she usually works on ministering assignments? Sometimes the Church servers get overloaded and give errors on Sundays.
