Lightroom mobile premium

Hi, I’m trying to purchase Lightroom Premium using my ₹170 Google Play balance earned through Google Opinion Rewards. However, during checkout, Lightroom is automatically selecting a different Google account that has ₹0 balance. My Google Play account with the ₹170 balance is already active on my phone, but I’m unable to select it during the Lightroom purchase. Could you please help me use the correct Google account/Google Play balance for this purchase?
