billing maintenance is over and here i have the same problem. can not buy lindens at all. my card is ok ( visa ) . used it to buy stuff online today. second life billed my account before and it went through. but not able to buy lindens today. before or after maintenance
( edit ) called billing support and they claim the bank is denying the payment. card works fine though when i pay for amazon , discord , ... so i suspect second life their system triggers something that causes banks to deny payments.
