[MCU] Quick question: Why didn’t strange see Thanos coming much sooner?

Thanos’s actions were pretty significant and peering very far into the future would have made his plans very obvious. Did something happen that changed all the timelines? Could strange not see past the snap, since he was destined to be dusted? Maybe strange decided not to peer into the future, until it became necessary in infinity war?

I don't think Strange ever looked into the future before Infinity War. Mainly because there's really no reason for him to do so but also because he needs the Time Stone to do it and he would never use the Time Stone unless it was absolutely necessary.
