Blocks page not loading

Just started using Thunkable for the first time and the blocks page isnt loading. I just get a blank screen with the blue conversation bubble in the bottom righr corner. Ive tried different browsers and devices over a period of two days and nothing. Help!

So, you click on a component from the menu on the left…select one of the blocks from the menu and drag it into the work space…and then it disappears?
