We have one person in our department that is an Owner that this rolled out to. She has training logs that use SharePoint lists to capture the data. These SharePoint lists have three lookup lists attached to them. Two of the lookups pull in add'l data like the leader and current/termed status. She uses datasheet view to copy in her training participants as there could be as many as 100 in each session. This worked well until the update. Now she can't use datasheet view to enter the trainings for more than one person at a time. Our IT department has confirmed this issue is due to this update. I hope this is being looked into. I am the secondary Owner of that site and I do not have the update and can still use the datasheet view to enter our training participants. So at this time I am doing her entries for her.
