Having experience in this regards is not something new anymore, this is to tell us how the network is busy or congested, but we can always manuever our own way through, try to use a bitcoin wallet like electrum which support RBF, adjust your transactions to the lowest priority, apply the option of static and set the limit to about 20 Satoshi per vbyte, make your payment and use the transaction id to pump your transaction, use via btc to make your transaction faster since it's a mining pool and it's free, another thing you can do is to target weekend transactions or study the mempool when it's less congested.
Take note that ViaBTC is a mining pool and if you use their free accelerator and meet all the requirements, you still have to wait until ViaBTC successfully mines a block, and it can take sometime. ViaBTC also accelerates only 100 tx's per hour, so it is likely that you will fall under a queue.
It is also worth mentioning that you must use above a certain fee rate to be able to accelerate your tx, also the volume of your tx cannot be more than 500 bytes. ViaBTC works anyway, but i would just check mempool.space and choose a fee rate that is best for my tx at that point in time.
