Dead pathlight

One of my solar pathlights stopped working a short time ago. It also will not charge. The battery was at 15% at the time but now it says on the app not available. I won't have time to call tonight but any thoughts or suggestions in the meantime?UPDATE: Just a few minutes after I posted this, the light started blinking and charging. Also, on a unrelated note, I recently got a replacement stickup cam. It came with a battery and I put it in, but I decided to keep using wired power. The battery will not come out. I pushed on the tab and pulled on the battery but it won't move a inch.
