I have one question about the gap limit in bitcoin wallet. If for example I create a 24 Word BIP39 Wallet in Sparrow Wallet and I sent some Satoshis to each one of the first 200 addresses. Then I decide to send the complete funds of all 200 addresses to address number 201. If I want to recover the wallet later on another computer using my 24 words is this a problem concerning gap limit?

The gap limit tells the wallet how many unused addresses to skip before assuming that none of the following addresses have been used. In your case, a wallet would see all 201 addresses in the block chain and not have to skip any at all.

There might be a problem if you sent funds to only the 201st address because the wallet would have to know that it might have to skip 200 addresses before finding a used address. You would need to set the gap limit to at least 200 in this case.
