Do you mind to share what you've done with this?
I've created an US Starbucks Account and loaded $20 with my Aspire card last night, very simple and easy. However, today I went to a Starbucks and ask to pay by the US Starbucks app, they scanned it but told me they can't find my membership. Not sure what happened, do I need to wait for a few days after I opened the US Starbucks account before I make the purchase with it? ....
I have only ever had issues at two Starbucks stores.
One was where the staff scanned the app but assumed that I was paying using Starbucks stars for some reason. I had no stars to use (and being a US account, could not be redeemed in Oz anyway). Once they realised that I was paying with my Starbucks balance, reprocessing resolved this.
The second problem arose when my account was not recognised on scanning the app. This was at a new store that had only opened that week. The manager advised that there was an IT issue that was still outstanding. Anyway, they provided the drinks at no charge.
By the way, I’ve had some staff tell me that as my Starbucks account is US-based (they can see that my balance is in USD), then it will not work in Oz. I then ask them to scan anyway, and lo and behold, it works.
. However, in your case, the app was scanned.
I would suggest trying another store, if you have that option available. Maybe there was some sort of operator error. In any case, I find that adding credit to the account is applied immediately. There is no delay. So, if you added $20, then the Starbucks app will show the updated balance within several seconds, showing your ($20) balance.
Edit: If no joy, then perhaps need to contact Starbucks Customer Service
