Consistently after a few cycles of edit slide & share to Facebook.
Eg. Delete body text, post, delete reference, post, add body text "abc", post, add ref text "123", post, change size, post, hang at the progress indicator during post.
Randy,
What OS are you running? Can you post your logs and if you are macOS can you use the Activity Monitor to sample the hang. If you are Windows can you get a proc dump using the Task Manager?
Thanks,
Philana
