Disable read-only warning in yellow alert

[bergie7isu]

Is it a new thing all of a sudden that Excel is warning me that my file is read-only in the yellow security message towards the top of the sheet? Can I disable that somehow?

To be clear, I want to keep the document as read-only, but I don't want to get warned about it every time I open it.

Update: looks like enough people complained and Microsoft pushed an update to stop this warning from appearing...
