Seems to be a bit of a bug on the LendingCrowd marketplace. It looks like there are 205 loans available (at the time of writing) but there seem to be quite a few loans with very small amounts ostensibly remaining, but when you actually click on them they show as unavailable.
Basically looks like just about anything with <£50 remaining lendingcrowd , looks like it applies to 50 odd loans at the moment at a very rough guess.
On a related note, aside from this display error, with even more early repayments yesterday ( I had 3 myself) I think we're almost back to normal liquidity. There must be plenty of borrowers off elsewhere with CBILS loans.
