Many thanks for your comment. You may be right ... Google Scholar released the metrics last year in early July (7 July). In 2019, it was released on 19 July. And in 2018, the release date was 2 August.
So ... here is hoping that the new metrics will be released very soon.
You are also correct re: manual calculation. I confess, however, that this option is probably less appealing if you are like me, i.e. interested in a rather large number of journals and their metrics, and in multiple discipline domains. :-)
