Hey, @MonikaRusso. Thanks for starting this thread. You're not the only one experiencing this with your store analytics!
Our developers have noticed that the analytics are being delayed for some merchants, and they are currently working on a fix for it. Rest assured it is just a delay, so it may be a bit slower displaying current data for yesterday and today’s activity, however no data loss is to be expected. Updates will be posted on the Shopify Status page.
Thanks for your patience, as we’re working to get this sorted out as soon as possible. If you have any other questions or concerns, please let me know.
