As of 5/22 (to my knowledge) the payment links generated by the square mobile app are not applying default tip percentages found in “default percentage tip” on the Square dashboard.
Payment links generated through the online dashboard are working correctly and applying a chosen default tip amount
When you say mobile app do you mean the Square app or is this your custom app that the links aren’t applying the default tip percentage. 
Hey, Bryan! I am referring to the Square App itself
Apologies if this is not the right forum for bug reports for the main app
Ah, okay. This Forum is for our Developer facing tools. You’ll probably want to post on the Square Seller Community
