my daughter was playing robloxs on my xboxone and someone stole her money 2 million

I dont think Game Pass has anything to do with the issue.

Both the games they are trying to play are free to play downloads that have been installed to run on the console.

Example 1 - Both want to play Fortnite. If Daughter A is playing and Daughter B turns on her xbox and logs in, it ends Daughter A's session.

Example 2 - Daughter A is playing Roblox and Daughter B loads Minecraft - it ends Daughter A's session on Roblox.

And so on.

Currently it appears that for some reason they cannot be playing ANY game at the same time and both have/are using separate gamer tags.

someone stole one of my xboxones trying to find the last 5 locations my profile was logged in

I hbae exactly same issue when trying to setup for one of my daughters. My other daughter i setup a month ago and it works fine in her profile. I do wonder if an option has removed/changed and the interface between xbox and roblox no longer works
properly for newly setup accounts

It was working 2 days ago

It might be that the tablet version of Roblox doesn't use the content restrictions set on your daughter's Xbox Account.

Roblox uses it's own account system, and if she is playing on Xbox, her Xbox Account settings might prevent her from using certain features.

As a parent, make sure your daughter is added to your parent account's family at
https://account.microsoft.com/family.

If your daughter's account is in your Microsoft Family, go to
https://account.xbox.com/settings and click on your daughter's account.

In the online and privacy settings, make sure your daughter is allowed to view creations from other people. Since the creators in Roblox probably aren't on her friend list, set that to all/everyone.

Also allow her to play online Multiplayer with everyone, and also allow her to play online multiplayer on other platforms.

Make sure to save the account settings under a category before you move to another category (i.e. set the creations from other people settings under the Online and Privacy category, save the settings, and then go to the Xbox One and Windows 10 category,
make the multiplayer settings, and save).

After you changed these settings, have your daughter sign out of her account on the console and have her sign back in (or restart the Xbox console).

Now, she should be able to play Roblox without getting Error 110.

Could someone possibly invite me to be in program ? My daughter wants to play her piñata game so bad lol
