Post the TXID and let's see if it's confirmed already. The mempool isn't that clogged anymore and the fees are way cheaper now.
FixedFloat will forget your transaction after 30 minutes and so if sent way after 30 minutes, my money is sent to the void.
If it's already sent there and you've got the link of your transaction which is also the reference number, it won't be forgotten. You have to save that link of your transaction so that you can still follow it up and check on which part of the process you are already.
