There were/are a lot of bug reports on the forum and the discord about not being able to purchase things or buy/renew VIP since the launch of the shop. The VIP issue specifically got addressed by Cordovan but only that one.
Customer Support only gave a standardized non-information answer to several different problems for over a month.
I gave specific details in my bug report/ticket to CS and not here because the forum can't help me with this.
They launched a buggy shop and were not able to fix it so far for many people. I never claimed that it doesn't work for everybody. I am very glad it does work for most actually. It would be even a bigger mess if it wouldn't.
Cheers,
Titus
