Issues opening and editing files in Excel Online

For the last 2 days all users in my company have been complaining that they cannot open or edit files stored in SharePoint Online with Excel Online.  When they try to edit, half of the cells are blank.  Once the sheet loads an error pops up that says "Something went wrong." and nothing more.  When we try to open sheets in the desktop app, we get another error saying the file is locked.

Is anyone else having these issues??
