If you login to your Google My Business account, click on one of your business listings and then go to the insights section, you will see that the graph that shows data for views on your Google Maps listings both in search and in Google Maps is missing data from this past Friday - the 13th. I am not sure if this is some sort of joke, I doubt it, but it is pretty funny that the data is mysteriously missing on this scary spooky day.
It is not uncommon for this report to be missing data, I believe it was missing data on the 6th of March as well.
Here is a screen shot:
They saw it was Friday the 13th and decided to scare us all. 😁

I see it on all my listings too. I'll ask them about it and let you know.
Don't be spooked, it is not just you, you are surrounded by people in the same haunted house as you. Google has not commented on this data loss but again, this is not that all uncommon.
