Bitcoin Address Lookup, Checker and Scam Reports ...

[Technical] Address gap limit - a problem with Bitcoin wallets or I'm doing it wrong?

I run an app which accepts Bitcoin payments natively, meaning that I generated an xpub with my trezor and I derive that xpub in my app using Bitcore library to obtain addresses.
Then, I register to a webhook on blockcypher for those addresses. I derive a new address for each new invoice.
The problem is that once I create an invoice, the invoice basically is valid "forever". It doesn't really matter if it's valid only for one week (it would be minimum a few days).
For each of these addresses, I subscribe to a webhook notification from blockcypher, so that my app is notified when a payment is made and can mark an order as having been paid.
However, it does happen that there are sometimes 20+ orders in a row that are unpaid. In this case, although blockcypher has seen the transaction and told my app that the coins are received, and the order is marked as paid, I cannot see them in my Trezor. I've tried all wallets (mytrezor, electrum, copay, mycelium) that are compatible with trezor and all have the same issue.
Essentially if I want to spend my bitcoins at this point I basically need to send microtransactions to the 19th unpaid address so that Trezor does the work to look at the next 20 addresses.
I believe this is caused by the address gap which is "standard" to be 20 addresses for HD wallets. I would really like to be able to force my wallet (even if it takes much longer to sync) to look up 100+ addresses.
Is there an automatic fix for this?
I'm aware that there are some hacks we can build, e.g. using mybitprices.info to generate a CSV of addresses and lookup balances like that but it's what I'm doing now and trying to avoid.
Thanks!
