You can see transactions on https://antchain.xyz/ but I'm glad you have already received it. I don't know the exact transfer time so far.

The repair button you can find in the menu top left: Wallet --> Open wallet database and then you will see a checkbox with 'repair mode'. But notice, this can only be done in the PC wallet.

I don't know if you have a PC wallet also because in your edit you say your ANS is in your web wallet now. On the web wallet, you can't claim the ANC at this moment. But I can ensure this due this post that it is generating ANC in the background, which you can claim on a later moment. And if you can't wait, you can try these steps and set up a PC wallet which I described in this post.
