Hi, the turndown arrow by the BRANCHES item in the left sidebar disappeared, and branches are no longer showing, when I reached about 300 local branches in Sourcetree. It reappeared when I deleted the newly added branch that caused the issue. Note that about 1500 remote branches show fine. I suspect that Sourcetree has a hardcoded limit for the number of branches, that may need to be raised substantially or preferably removed.
I found this question demonstrating a similar issue with a subfolder:
And posted this comment for a similar issue on Stack Overflow:
I'm on Sourcetree 4.2.8 (265) on macOS 13.5 Ventura with system git 2.39.3.
