AKA Icon solos are there any?

Yes, it’s called the AKA Iconoclash and you find it under solo seasons. You have to beat it to earn an AKA Icon token. There are currently 10 available so if you haven’t done it yet you’ll have some grinding to do. There was a glitch that if you played the LaDanian Tomlinson challenge under week 23 of the Legends challenges it would track against the AKA Icon field pass for some reason. Not sure if it’s fixed yet but worth a shot to try it out as it would save you a lot of time.
