Hey guys, has anyone managed to create a NEW Polymarket account after April 2026 and successfully trade via API? I'm stuck with this error when posting orders: `the order signer address has to be the address of the API KEY` Already tried: - signature_type 1, 2 and 3 - using the deposit wallet as funder - placing a manual trade via UI before hitting the API - manual patches on both Python and JS SDKs - recreating the API key multiple times Old accounts work fine. Only new accounts seem broken. Anyone solved this? What was the fix?
