Solar cam charging issue

I have a Solar cam, it’s installed in a good location and I can see it’s charging so it’s getting sunlight. I’ve been watching the icon now for almost 2 hours and it’s been constantly charging. However it hasn’t gone up a single percentage. Any tips? Seems like an issue to me.

Have you tried refreshing the app? I’ve noticed this with my doorbell cam. When I’m charging it I’ll notice the percentage of battery doesn’t increase. If I close the app completely, like not have it in the recents, then open the app later I’ll notice the percentage of battery has increased.
