Ever since the LFG update, the xbox app on my iPhone will no longer send messages.

It either gives a ridiculous error about my privacy settings, or says the contact doesn't exist.

I can send messages using the Xbox app on PC, so my privacy settings are clearly ok.

Is anyone else having this problem? It's driving me crazy and there isn't much hits on google for this issue.

I spoke with a guy via their text chat and he said they had reports and were working on a fix... update came out today and it's still broken, so I'm really hoping it's not just me.

Thanks in advance

EDIT: Xbox support provided me with a fix. Quoting their response:

Hey there, very sorry to hear this! Our teams are still looking into that. In the meantime, please go into your iOS settings, then the date & time settings, and turn on 24-Hour time. Can you let us know if messages are sending after that? ^BD
