I Can't Invite People In Brawl Stars

I am a Brawl Stars player on iPhone and my in‑game name is “Da bois”. Until a few minutes ago I was able to invite friends and play with them without any problems, but suddenly the game stopped letting me invite anybody. Now every time I try to invite someone it just doesn’t work, so I cannot play with friends at all, which is very frustrating. This problem started only about five minutes ago and has been happening every time I try to invite someone since then. I have not made any in‑game purchases recently, and I have already restarted both my iPhone and the game and checked my internet connection, but nothing has changed and the issue continues. I kindly request that you check my account and fix whatever is preventing me from inviting other players, or inform me if there is any setting or restriction on my account that I should change so I can play with my friends again.
