[BR] Not letting me use Supporters turn 1. I am trying to play an older Expanded form

Not letting me use Supporters turn 1. I am trying to play an older Expanded format, but I can't since said format allowed the use of Supporters on turn 1 going first whereas TCGONE's Expanded does not let you do so.

Triage Agent: Which format were you playing (its name in the format list)? “Expanded (BLW–CRZ)” follows the rules of its 2023 season, when the player going first couldn’t play a Supporter on their first turn either. If you meant an Expanded season from before that rule change (2018–19), that format doesn’t exist on TCG ONE yet. Let us know which season you want and we can look at it.
