Update

Someone said you can't edit any post containing an image, and my oldest post has an image. Might not have to do with age at all.

I would edit my title to reflect this but.... ¯\_(ツ)_/¯

Just playing, Lj, keep up the good work!

I can still edit newer posts with Sync, but not my oldest one. I've only made three posts, so I don't have much data. For all I know, the bug is you can't edit your single oldest post. But I do know that Reddit would archive posts after a while, and maybe this behavior is a throwback from the Reddit version.
