Hey, thanks for the report. This is a confirmed bug. In split diff view, the expand unchanged lines button only works on the first click, then it stops responding. We’ve logged the issue, but I can’t share a fix timeline yet.

As a temporary workaround, switch to unified diff view. Re-expanding lines works correctly there.

I’ll post an update in the thread as soon as we have one.
