I am having same issues currently I made a transfer of 0.00142BTC and the transaction fee was charged about $4 so I had to readjust the fee to about $1.7 since then till now there have been no confirmation but when I scanned through tx id, saying payment received but not yet confirmed. This has kept me worried for over 6 to 7 hours now and does this mean it won't be confirmed again anymore?
Your transaction may take a longer time to be confirmed since your transaction already broadcast and received 1/6 confirmation, but certainly, it won't be cancelled since it has already been broadcast the minner is just waiting for the network to become less congested before the transaction goes through.
But Op's own situation is different from yours since he uses low fees and that results in no availability of any miner to broadcast the transactions and after the duration of the stipulated waiting time the transaction has to be cancelled, If you use Bluewallet you have a point where you may boost the transactions fees by adding more fees to get the transaction accelerated with high priority.
