On any sites that respect themselves and their clients, this should not be, the administration should not be silent, if something is wrong with the traffic or bitcoin wallet or other problems arise, then they should warn or write to their users about what is problematic and they cannot pay, and therefore payment is canceled.
But that's my personal opinion. With respect to the site administration. :)
My bitcoin wallet is normal and working, but I still have a few wallets, and I can change it at any time, but how can I understand that it is problematic in my wallet and for some reason cannot be sent to it if the administration is silent and does not comment on the reasons cancellation payment request.
But the cancellation occurred not only at my account, two people wrote about the same problem, and one of them also had a payment request on bitcoin wallet.
