after using for 2 months - my solar has also stopped charging.
I thought it has a virus… Spoke to Ring tech support in Egypt - very helpful custmer service but been asked to send back my old solar panel to be exchanged.
I charged both battery to 100% and reset camera and setup again - no luck!!
Let see if a new panel would help??
I personally think that the battery is not compatible with the solar charger - the battery takes 10hours to charge on the mains!! how could a small solar panel charge the battery??
