“I read through everyone's comment as much as possible to make sure this wasn't already asked, but is this a part of an update to Excel 2013 via 365, too? Alternatively, do we have to install Excel 2016 via 365? Many of our in-house application add-ins do not support 2016 (very well, at least) just yet.
Will I need to wait? I'm terrible at waiting. :'(”
