Does Unpublished version bug still exist?

I keep reading about the Unpublished version bug, but most posts were at the end of 2019. I am having the same issue on my Roku Stick. Feeds are good, content has been ingested, but on my device, all I get is the Search and About buttons. On Preview within roku account, I see all the items correctly - just not on the device.

Any ideas?

You should also make sure you are on the latest firmware. Additionally, you may want to try removing the channel and readding it.
