Been having the same error for weeks every time i try to post a new post. All they can say is to turn off my wifi and redownload the app. I have done everything as a technical support my self, yet it didnt work. Their customer service is so rude, as they are asking me to do exactly the same steps again and again, giving me the impression that I am stupid. At last i deleted the app as they couldnt fix it.
