Video Doorbell 3 Plus dropping offline

Over the last couple months I've noticed my "Video Doorbell 3 Plus" dropping offline very frequently. Initially I thought that the battery kept dying so I kept charging it and replacing it but then I noticed it was happening so quickly that it couldn't be the battery. I confirmed that the battery is still nearly fully charged even though the doorbell is completely unresponsive. I can also confirm that it's not the Wifi connection because the doorbell doesn't even respond when I try to press the front button...it's just completely dead until I take the battery out and put it back in again. What can I do to diagnose and fix why this is happening?
