My annual 'big spender' moment... I have no idea why, but from the very beginning, I couldn't pay for Premium on the desktop version of Twitter. I could only pay using my phone, and the annual fee for Premium+ on the desktop version is only $398, while the iOS version costs nearly 700 SGD, which is about $553—an extra $155. I tried every card I could: Hong Kong debit cards, Singapore credit and debit cards, Chinese credit and debit cards, U.S. debit cards, and even the two U Cards I have. I tested them all, and I even switched between Mac and Windows computers to test again, but none of them worked. What kind of nonsense is this? In the end, I used Apple Pay on my phone, and it went through instantly... but the price was way too high.
