Arlo Ultra not connected

[Jim12]

I have two Ultra cameras. I had not charged them for a while. Then, I charged both cameras and one is working properly and the other is not. Specifically, the second camera cannot be discovered. I removed it and tried to added again without success. When  I connect it to charger, blue light blinks for few seconds and then there is an amber light for a second and then no lights. I left the camera to charge for over a day and still cannot be discovered. Any suggestions will be appreciated!! Thank you so much!

Swap batteries around to see if it's the battery or camera.
