The second one, this was present in the previous release too, the combobox to pick the right intent opens at the bottom, stretching the main container, I must scroll down to see it
In my case the first problem is also showing up when sharing a link with a guest tester.
I am running Rasa X 0.28.4 using Docker-Compose Quick Install.
I have a custom action that displays buttons, and after selecting a button there is no scrolling showing the bot’s reply and the input box for continuing the dialog with the bot.
I have checked that the bot’s reply is there by opening the Rasa X Conversations pane.
There is no scrolling also in the Talk to your bot pane, unless I do back-and-forth with a different pane each time.
