Hey @Alan_G, thanks for the follow up!
There’s a very similar bug that affects BXGY discounts when upgrading one or multiple lines of a BXGY discount to a selling plan.
To reproduce it’s similar to the previous bug that happened when changing the cart line variant, but this time instead of changing the line variant we add a selling plan.
You’ll see that the BXGY discount disappears and only the subscription discount is applied.
This does not happen if, for example, the two lines of a BXGY are different variants or have different line properties, just like with the initial bug mentioned in this forum post.
Do you have any ETA for when this will be fixed?
