Child EA account can't access FC26 online — stuck in AI support loop

I'm in the same boat, and I was on chat with a human (I think) and he said theres nothing he can do,  "this is out of my reach as you know I am just an ordinary chat support advisor and there is nothing much in my hands". So if anyone else has this problem, don't waste the hours I did...

I have this problem with the FC26 app on Android.  My son has a child account which I set up for him.  User ID only, no email address.  The FC26 app on Android has only an email field to log in, so he cannot log in to play the game.  In a previous version of FC Mobile, there was an option to sign in with Google, but this option isn't available in FC26.

The process to just create his account was fraught with friction.  It was one of the most user UNfriendly experiences I've had online, and after going through that process it turns out that his account cannot even be used.  The support process is absolutely woeful, making me wonder if there is a single human in EA's support team.  The hours I have lost on this to get this soccer-mad kid onto a game that he is dying to play (and isn't Roblox or something equally toxic) is ridiculous, and I'm still no closer to a solution. 

What's going on EA? This is amateur hour.  Actually that's discrediting amateurs - at least amateurs will try; you guys don't seem to give a sh$t.

It is not a switch 2 problem, I have switch 1 oled and a have the same problems, please EA do something 

Having same issue.  Maybe it’s a switch 2 thing?  If anyvody has any insight let me know.  I think it stems from the fact that a child account only has a username and not an email address and in fifa, you need to enter an email address for login.

I am in this same exact boat it seems...although I haven't gone through the chatbots yet. My 10 yo loved watching the world cup and was excited when he heard the FC 26 game was on sale. He spent his own money on the game, but we're in this dumb loop.

First I couldn't even create an EA account for him on my phone, it said it required a Mac or PC. Got past that finally, but he can't actually access the online options for gameplay and building out his own team. 

We got it on Switch 2, and I was aware cross platform play was not an option, but we figured there would be some of these online options; we also understood with the child account that voice chat likely wasn't going to be an option, which is fine as well. But he can't even sign into his account on the game. It takes him to the sign-on screen which ONLY ALLOWS email addresses from an account, doesn't allow his account to login due to it looking for the email address format. 

So yeah, it would be great if EA could A) make it possible for him to play the game as it should be and B) Make account management sooo much easier by allowing for all 3 options when signing in (email, username, or phone number)
