Solar Pathlight repeatedly flashing and going offline and back online

This afternoon, one of my solar pathlights started going offline, back online minutes later and back offline minutes later. I brought it inside to charge (the battery was about 60%) and instead of blinking while plugged in, it repeatedly flashed. I removed it from the app and readded it. The light periodically flickered and started flashing again after finishing the setup process. The battery charged all the way but the light still flashes and goes offline and back online. I readded it to the light schedule, but it did not come on at dusk with the rest of the lights. It’s still flashing.
