Stuck despite 419.858 sat/B

[Bitannoyin]

I've sent over $6,000 with a 419.858 sat/B fee, which I thought was more than sufficient ("priority" fee on blockchain.info. lol!), but over 2 1/2 hrs later I'm still at 0 confirms.  My buyer has given up and gone to sleep. This is giving me such a headache. Do i really have to pay a tx accelerator and risk even that not working?

Looks like it took a little over 3 hours... but it confirmed.

The lesson to be learned here is that you shouldn't trust b.info... it is a terrible wallet. Make sure you check https://bitcoinfees.earn.com/ and https://btc.com/stats/unconfirmed-tx BEFORE you send a transaction to see what fees are actually like.
