The Shopify-native tipping feature of checkout completely breaks when used on a checkout page where the cart contains products with selling plans. The tipping box shows up, but interacting with it produces no effect, i.e. it’s impossible for the buyer to leave a tip.
Here’s a short screencast to demo: https://monosnap.com/file/k9UQP3QatpnFD8hv3s5vWEZBYceBWD
There’s nothing in the documentation of either selling plans or tipping about limitations with tipping, so I assume this is a bug on the Shopify end? Please advise.
