Commits are missing from branch commits view

We just encountered a weird error in the Commits view. When develop branch is selected, Bitbucket claims that there are no commits to display.

‌

When selecting “Show all” There are only some old commits visible from November 2018.

I cloned the repo for testing purposes and it seems that the branches actually are OK and all the commits are there. So, the problem may be in Bitbucket.

Tested with two users, Chrome, Firefox and Edge.
