You complete your database, and the company begins using it. Shortly afterwards, two GearUp buyers, Cora and Owen, work together
on a sale from a supplier called TennisSource. Both come to you complaining that their entry into the "Supplier History" part of the database is not showing up. Instead, the field reads "invalid entry." What is most likely the problem?

The multi user issue rises when the users concurrently access the data from the database and related error get invoked due to some reason like repeatable reading issue, serialization, etc.

Format painter is that icon tool that looks like
a paintbrush that is used to pick up formatting of an existing text and then

more than one element, you should double-click the format painter and press esc
key to deactivate.
