OK, thanks for reporting. I've removed an update from the server that should fix it.
How about now?

Unfortunately, no.
I made a new post and it worked well, and all the 3 posts (they were merge into one post) that I have made yesterday have reappeared above the new one. So I deleted these 3 old posts and the new one suddenly disappeared (I think it's still there, it's just hidden). Can you see it somewhere ?
Someone replied with success in the thread. I just posted my last workout and it worked. Maybe the problem occure when I'm posting twice in a row ?
UPDATED : I posted a test right after and it worked. So we will see next time I'll post...
So, you're saying it is fixed now or?

I just posted again and it worked. So far so good.
