Ring doorbell 2nd generation is missing motion and is slow

My doorbell 2nd generation has been missing motion. I literally had someone come up on my porch and leave something on my door and it didn't detect or record it at all. The wifi signal is good, i tried rebooting the doorbell on the app but keep getting an error message and to try again later. I changed all the settings to the recommendation on the app. Since changing the settings it isnt notifying me at all now. Please help.
