October 2019 security update - Live on T-Mobile

I received my G8 yesterday in Ireland from a US Ebay seller (Sprint unlocked)
When I powered it up I think I had 4 security updates, one after the other, the final one being October.
I am extremely pleased....... I was worried that taking the phone out of the USA might hinder my updates.

Update on this.
I had to send the Sprint model back as I couldn't get it to work on my data network (only 2G)
I just received an AT&T model which I have working on my data network but this is stuck on its original March '19 software and won't update.

Bummer!!!
