Seattle airport – connecting flight for european

Hi everyone. I’m a scot, living in Ireland flying to Vancouver for a wedding, and on my way back I have to fly from Vancouver to Seattle and then to Dublin. I booked this before things got mad with airport security and customs and increasingly considering moving my return flight to go Vancouver -> Toronto -> Dublin. However, it’s gonna be an expensive transfer this close to the date.

My question is has anyone had any seriously bad moments (or heard of any shockers) in seattle airport the last couple of months with customs and border control? Should I definitely shift my return flight or is it a non-issue and reading into this too much?

Thanks!
