[AC Question]

From phone camera, some photos cannot be shared when I am accessing my Facebook Upload Photos.

My phone is Galaxy 6s, and I'm accessing fb on the phone. Not all of the photos, just some random ones it appears to me. Is this a phone issue or a Facebook program issue?

Considering things, it's probably a Facebook issue.

When will it be resolved? Who knows if it ever will? Facebook isn't exactly known for fast responses to app problems.
