Has anyone used Chase Pay at Starbucks? Its an adventure every time.

1/2 the time the cashier doesnt know how to scan it... I have to tell them which scanner to use. (they try to use the big bulky scanner used for gift cards)

And when they do know, and they hit the correct Chase Pay button on their register, it takes anywhere from 2-6 or more times scanning my phone for the transaction to go through. This is not their fault...it appears to be the software.....as sometimes the first couple times it said "Invalid Card"...until they try it again and it finally goes through

You could imagine the holdup sometimes at the drive thru....

This issue occurs at every Starbucks I go to....and has not improved over the 3 months I have used it.... Whats odd is that they tell me they get no support from Chase ....so why is Chase Pay advertising Starbucks on their app if they give no tech support on it to their vendors?
