I think this is the problem with many virtual cards, and it's even bigger problem if you had to perform kyc verification and send them your documents.
Another virtual card I was testing recently was added to Aliexpress without any issue, but when I tried to make a purchase there was some error message and I couldn't complete purchase.
Maybe Aliexpress should also be blames for errors like this
Initially, before all this chaos, I never encountered any error while making purchases using the virtual card via AliExpress. The maintenance error also appeared as soon as I had added more funds in the account, not when I was trying to purchase an item.
I set up an account with Cardrypto/alchemy pay and I have so far been successful subscribing to Tradingview paid service. I will update how it goes with other services
I am really disappointed in the Pyypl card service. At the beginning, their services were too good, though the support system was worse from the beginning. I have used their cards in many marketplaces and services when they were with Mastercard. I think their visa card gave service for a few times and shut down again. I have to find an alternative card service to avoid such an issue. I am going to withdraw everything from Pyypl and come back when their card service works perfectly. There is no meaning in holding funds there or using their services if the card system that we need is not working anyway.
Very disappointing indeed. Better to keep funds off their service just in case.
