Hello @cmgorton, can I take this up?
Looking for opportunities to improve in Ruby(and Rails) since I am extremely new to it.

Thank you for assigning it to me @cmgorton. I will start working on it soon.

I just unarchived several of my old previously unarchived posts with no problems. Then I archived another post and unarchived it a few minutes later. However, I did notice that the UI does not update until a hard refresh, so it can look a bit confusing.

Hey @cmgorton, apologies for taking a lot of time to start working on this issue. I am currently swamped with work at my organisation. Please assign this issue to someone else for now. I will get back in touch once I have more time.
Thank you!
