Have noticed recently (not sure if there has been an update) the following two issues:
1. I get notified that I have a new message. I click on the notification and it brings me directly to the space. I then cannot see the new messages unless I exit the space and go into it again. Also, when in a space, when new messages are posted, you often cannot scroll down to see the new messages unless you exit and enter the space.
2. If you view an image in the space, this works fine. But when you press the "back" button (<--) top left, it exits the Workspace app completely. When you open the Workspace app again, it's still showing the picture. The only way I've found to get back to spaces is to complete shut down the app out of background memory and re-open which then shows spaces as it should. Annoyingly reproducible.
