I have 5 Eufy Solo E40 Cameras and 3 will not switch to solar panel from battery in the app but have charged and stay charged. The blue charging indicator light will not go away because the app says they are on battery mode. I’ve remove and reinstalled the app, unplugged the solar panel abd reinstalled ,restarted the Cameras and nothing will change in the app. Eufy tech has been no help ,as usual.
