It says my gamertag is an invalid gamertag

Until yesterday I’ve had no problems with waypoint I usually check it on my computer yet lastnight after playing I checked to see my progress and it shows me a recruit.I am 74% to inheritor and have had this gamertag for a while now.I just don’t understand why my husbands isn’t having any problems we play together all the time and do all the same things regarding waypoint.I was wondering if anyone else has a problem like this or does anyone know where I can go to get help to fix it thanks.

Try playing a few games, might force your gamertag to readd.
