I write it, push post, see the note "posting...posted" and then update timeline. And it's not there. And not under my profile. It's just not out. Same for responses. Small text message isn't posted in same ratio as pictures or so, size makes no difference. I had now two days problem with loading pictures on weak wifi, but data went ok and now it continues on home wifi. I don't know if it's the app, but what else?
