I thought I was doing OK - all filled apart from the unclueds, plus 15d having two possibles. I then started using Excel to get possibilities for the unclueds. But I’ve just spotted that in my anagram version, 22a has two unchecked digits. The only way I can see that that resolves unambiguously is if they are identical (which I don’t think they can be), or if putting them one way round would give a number used elsewhere in the grids - which isn’t the case for my current set-up.
