Looks like I can only see the three latest versions (as far back as 2.0.12). Is it user error or do I need to do something special to look further back?

Put it in the Signal chat!

Same here, though I do have one thing I miss from Sync: press+hold on an image in feed to make it full screen. Happen to know if there is a voyager setting to enable this functionality?

Co-workers mocking me on the daily was all the source I ever needed.
