I am working on Magento 2.3.7-p3 with BrainTree Payment module (V4.0.9). I added a Bundled product to my cart. And I applied a coupon code (discount) on this product. On payment submission, I receive error from BrainTree payment module - "Amount must match the 3D Secure authorization amount"
If I remove this coupon code, the Payment goes through successfully.
I dont have this error with simple products or Configurable products (With applied coupon code).
