We noticed this situation with sending ADA to a wallet using addresses generated from cardano-address (according to the specifications on https://github.com/input-output-hk/cardano-addresses) which are separated by more than several hundred.
When we send a payment (from Nami or CCVault or wallet-server for example) to an address that is generated by the 2000th key (for example, it just needs to be something more than a few hundred above 0), we see that the transaction posts to the blockchain but is not recognized by any wallet (Nami or CCVault).
However, when you send payment to an that is recognized (something within about 200 addresses from 0th address or 200 addresses from the previously wallet-recognized transaction), you can sequentially increase the addresses by about 200 until you reach within 200 of the initial high-numbered address and then the transaction to the high-numbered address will suddenly appear (even if it is days later).
Can we be certain that the high-n incremented addresses will post to a wallet for verification?
Here is an example of two days worth of transactions.
