Market data in sandbox account

[az-z]

Hello,
as per: https://developer.tastytrade.com/sandbox/ :

Not every service is available in our sandbox environment. The following services are only available in our live trading system currently:
Symbol search
Net liquidating value history
Market metrics
Market data

But https://tastyworks-api.readthedocs.io/en/latest/market-data.html doesn't seem to mention the market data's limited availability.

Could you clarify?
It sounds odd not to provide market data (even delayed) for sandbox accounts.

Unfortunately sandbox accounts are pretty much useless for all intents and purposes. See #293 for a discussion of an alternative I'm working on
