[solved] Please, restore the responsive Live Test Web

I choose Thunkable to develop my responsive web-app. It’s not perfect, but I’m satisfied. With continuous improvements, Thunkable can be wonderful for building web apps. But, now I can´t test my app anymore, because I can´t find the link to responsive Live Test Web.

I can´t test with non-responsive Live Test

Please, restore the responsive Live Test Web.

Was just a temporary bug, I believe.
