Ben Tossell & I put together this app today with a technique we learned from @Robert_Petitto which allows you to create an approximation of a messenger-like experience. You can check out Robert’s original here: https://messenger.glideapp.io/
Thanks for the shout out!
Did signing in with Google remove the need to sign in again when adding a comment? I know this was an issue with my app where users would sign in and then when creating a chat, it would ask them for their name/email again.
