[Solved] Can I Change Firebase Connection settings at runtime

The issue reported in this post [Solved] All published Apps stop Working! Urgent help please! was effecting all and I myself was not able to login using the blocks but was able to login using the API endpoints.

I would stay away from a web viewer if I am targeting the independent run of the app from Thunkable server, I do not know for sure but it is issuing an iframe element which need to reside in a server.
