For the last several weeks, I have created a new branch in my file at the beginning of each week, merged that branch at the end of the week, and then created another new branch for the next week, and so on. That was working well, and I could see all of my old, merged branches in the Archived branches tab. However, a few days ago I noticed that I only had one archived branch available; all the older ones were just gone. What happened? My team was planning to use archived branches for reference, and now I’m worried that I can’t trust that feature for this purpose.
