Usage Metric Reports Not Updating Correctly

It seems like the usage metric reports (I only have one set up for one workspace) has stopped updating as expected as of 22nd Jan. For example, the usage metric report is showing that nobody accessed the workspace or app in question on Monday 22nd Jan and only one person (not me) accessed it on Tuesday 23rd Jan. This can't be correct as I, along with other members of my team, accessed the workspace and/or app on both 22nd and 23rd Jan.

Is anyone else experiencing the same issue?

Thanks,

Steven
