I’ve completed all of the theme team remix challenges except the tackles challenge and I’m still 10,000 XP short of Thomas and the unfinished challenge is only worth 1,000 is this the same for everyone else?
No, it's not the same.
There have been known tracking issues with TTR XP for some people though. Perhaps you've been one of the unlucky ones?
If you'd done everything XP wise minus House Rules (every set of daily objectives from the day part one of TTR dropped, Stats, H2H/Solo Battle objectives etc) and everything tracked correctly, you'd have been able to have had enough XP for Thomas by Friday June 9. And obviously sooner than that with successful HR objectives completed.
That challenge is worth 1k for everyone. Have you been doing your daily objectives every day? Because missing some of those is the easiest way to explain why you're short 10k on your field pass. Unfortunately, it may be impossible for you complete this field pass with the number of days remaining.
Daily objectives were necessary, I believe. Sorry bud
