I have the app 3.10 (667) and web page open on my iPhone 6, iOS 10.3.3.
i can't post to a 1:1 on the app, but I can on the page. But what's worse is the error flow on the app. It doesn't let me retry, it doesn't let me copy my message, it doesn't even let me see what I've just written, it just covers it with an Ok error prompt and removes the message in the background.
ive started writing my messages and copying them before posting them and ultimately just switched to using the website instead on my iPhone.
the app really needs to improve on the basics, i shouldn't have to retype a message, especially not if there's an error sending it to the server - that's where the native app can shine by holding on to these messages locally and even pushing them to a list or the clipboard to make recovery easy. At the very least I should be able to see what the contents of my undelivered message were so I can find some way of delivering it
Thank you for reaching out with this issue. Since this will require unique troubleshooting, I am going to open a case for you.
