Hey neighbors! Thanks for providing this information to us. I will make sure to pass this onto the appropriate team. To further confirm this concern, please do the following in the Ring app:
Visit the Main Menu > Devices > Select camera > and then select Live View. Let us know if the day appears correctly from this section of the app.
Once confirmed, return to the Event History Timeline view from the dashboard. If the date is still incorrect, please remove the Ring app, reboot your phone (turn it off/on), and then reinstall the Ring app.
If the date is still incorrect, please provide a screenshot of this so I can pass it onto our team. We appreciate your patience in the meantime, and thank you all for being the best part of our Community!
