It get sent, but does not get received.
You should check (using for example blockchain.com) the progress of transaction - is the transaction visible? pending? confirmed?
If transaction is waiting in mempool for a long time, it usually means that fee is too low. Do you remember which fee you selected?
You may use page https://jochen-hoenicke.de/queue/#BTC,24h,fee to see what is the current fee needed to have transaction accepted (at this moment around 30sat, during weekends it could be 1-2 sat, all depends on number of transactions and number of blocks processed).
Do you have one address loaded or many? Check if you have only one output in transaction or many. Maybe amount which you do not see was transmitted into "change" address (but then should be visible in the wallet) - if this is the case look here https://bitcointalksearch.org/topic/why-there-is-change-address-5373169
