Mastercard Travel Pass

Happy to Mastercard travel benefits, but I was requested to shows the app... after installing and queuing, it shows: "It's detected that your device fails to pass the compatibility testing and it may have been modified. Please STOP using this App ok this device", and the app automatically close. Unfortunately, the only way to access to lounge was by using the VISA.

Cant register my supplementary card, cause it keeps saying my credit card number is already registered, despite FAQ claims i should be able to register both primary and supplementary cards as long as they are under different names. No way to contacting them is really annoying too. Called the bank, said clearly this is an app issue , NOT a bank issue. I want someone to contact me or tell me how to pass first step to fix my issue.

Its a scam!!! Many of my friends experienced what I am experiencing right now..the app does not work. I have unistalled and installed several times and it keeps asking to update where there is no option to update. Mastercard and banks..they are fooling us in the name of Lounge access. I have international credit card valued almost INR 1 million and i use it regularly for transactions ,still, i have not been able to access any lounge so far. Total Scam!
