Stick Up Cam (Battery) thinks the battery is actually a solar panel

I had to swap the battery in my 2nd Gen Stick Up Cam in the back garden last night (as I’ve done many times before). Put the newly charged battery into the cam & it powered up. BUT when I look at it in the app, it says “Add a battery” and say the “Solar Status is Connected” (I don’t have the solar panel at all!) It shows as online, & I get movement notifications, snapshots in the main app page etc, but it won’t let me do a Live View, access audio, etc. What can I do to fix this?
