I am missing my Copper Membership that was paid for.
Don't worry, if you sent the btc to the correct address
[as shown when you pay] then you only need to wait for at least 1 confirmation before you can continue with the next step. Please be patient, but you must make sure you have sent to the right address.
Maybe the confirmation is bit long because the mempool is stuck as dkbit98 has explained. 40 satoshi per byte is the recommended fee, but if you are using wallet that supports RBF, then you can pay higher fee to get faster confirmations.
