My text isn't showing in party chat

1. Turn off your console by holding the Xbox button  on the front of the console for approximately 10 seconds. The console will turn off.
2. Turn your console back on by pressing the Xbox button  on the console or the Xbox button  on your controller.

If you don't see the green boot-up animation when the console restarts, repeat these steps. Make sure that you hold the power button until the console completely shuts down.

Important If your console is in instant-on power mode, the above steps will shut the console off completely. Instant-on mode, or the ability to turn on your console by saying "Xbox on," won't be enabled until you restart the console.

Hopefully this works but if it doesn't keep up updated.

Try this procedure, hope it helps. You can enable the Text Conversation Chat or Speech Conversation Chat features. To do this:- Go to the game's main menu and select the Settings tab. - Enter the Accessibility submenu. - Select Enable Text to Speech Chat or Enable Speech to Text Chat. To mute or unmute the microphone, highlight your Gamertag and press the OPTIONS button. In-game chat is enabled. You cannot hear party audio and the party cannot hear your voice. To switch to party audio, select [Party Settings] > [Chat Audio].

Hope I helped and see you soon

Xbox uses voice chat (party chat). There is no text chat in Roblox on Xbox One. It was removed awhile back.
