How can I make sure that the app doesn't apply bundle discounts on auto-charging subscription orders?
To prevent the app from applying these discounts on auto-charging subscription orders, go into Bundler > General Settings > Subscriptions. There, first turn off the "Seal Subscriptions" integration (in case it is turned on) and then change the value for the "If the cart contains an item with an auto-charging selling plan" option to "Skip bundle discounts, but keep auto-charging subscriptions."
