TEAMS TAG bug

So here is the thing.

I created a team with my friends and everybody was happy, suddenly there were some issues with the teams and I saw that RIOT said they were aware of the problem and they will fix it. The thing is all my friends got the team tag back except for me. I don't know if I'm the only one with this problem but since I created the team it appears that I can't go back in or be invited by other person.

Do someone have any knowledge about this or what can be done?

Thank you.
