I've been frequently purchasing Uber gift cards on sites such as Airtime Rewards or occasionally Amazon / Tesco gift cards if they have an offer. Until yesterday, I've always been able to add the 16 digit / letter code to my Uber account as a voucher code so I can use it on both train tickets and rides. Yesterday though, I got an error code when adding it with a message that I couldn't add it and instead, needed an Uber money account. So, I created one and, as has been mentioned previously, can't redeem the Uber money balance against train tickets. Any idea why the same type of code couldn't add as a voucher code and whether I might have this problem going forward as I've been forced to open an Uber money account and would like to go back to getting a code, entering it as a voucher code and being able to buy train tickets? Thanks.
