How long does Moralis re-index NFT data?

For some NFTs, the metadata property is null for some reason. Also, the is_valid is 0 and syncing is 2 which I presume is “still” syncing or there is some problem syncing the data.

    "metadata": null,
    "is_valid": 0,
    "syncing": 2

I wonder how long will Moralis reattempt to resync or reindex invalid NFT data?
