Why do i sometimes need to use old style symbols?

Hi,

Im using alpaca-py with a paper trading account. I can put orders in with new style symbols (ie: BTC/USD) but if I try and get_open_position with “BTC/USD” I don’t get a response. If i use BTCUSD then i get a response. Similarly, get_all_positions returns positions with the old style symbols for crypto.

The docs say we need to use new style symbols by sept, but clearly they’re not working yet.

What are other people doing?
