BCH wallet doesn't sync if it ever received OP_RETURN txs

Ledger Live Version and Operating System

• tested on Ledger Live v2.39.2, master + on some older versions, and seems like it has been broken since forver.
• Platform and version: Ubuntu 20.04

Expected behavior

Basically, your API returns <unknown> address value when output is OP_RETURN (it has no address, can be seen/tested here). Then somewhere else in a code there is a call to toCashAddress which throws for OP_RETURN outputs because it can't convert <unknown> string into a valid bitcoin cash address.

InvalidAddressError: Received an invalid Bitcoin Cash address as input.

I am pretty sure it worked fine in the past so probably https://explorers.api.live.ledger.com/blockchain/v3/bch/addresses/bitcoincash:qz00gq5knkfc9m4ejepcawzgl2fxzznvquc5cnfnkf/transactions just used to not include OP_RETURN outpoints.

Can this get addressed? I am not able to use my wallet because of that.
