Quoted from ForceFlow:I encountered the same issue when attempting to preview before creating a new thread. The thread then would not be created and I had to copy, refresh the page, paste, then create without previewing.
Counter-example - it worked fine for me... I've been meaning to create a thread about TransferWise, so after reading this I decided to try to replicate it when creating thread. I spent about 15 minutes typing the message - purposely spending a lot of time despite not really generating much message (https://pinside.com/pinball/forum/topic/anyone-use-transferwise-can-you-share-feedback#post-4444744) and then did a preview before posting. Thread created fine without an error. MacOs 10.14 using Safari 11.1.
