I am new to crypto so please pardon my naivety. I can't reach dev on PM because I am a newbie for this forum so please can someone help me here?  I sent some XLR from old wallet to an exchange and the transaction has not yet been completed after 3 days. What am I missing here? I understand that there is a new version of the wallet released on 12 January, will this XLR be sent after I install the new wallet? If not, how to then recover the XLR or complete the transaction? On blockchain explorer, this transaction id doesn't exist!

Below are the details of the transaction:

I am new to crypto so please pardon my naivety. As my title suggests, I sent XLR from old wallet and the transaction has not yet been completed. What am I missing here? I understand that there is a new version of the wallet released on 12 January, will this XLR be sent after I install the new wallet? If not, how to then recover the XLR or complete the transaction?
