Hi @TParsons,
We also have issues with the textbox component with Hebrew. When selecting the Rubik font, as you suggested, we get to see Hebrew but when typing in Hebrew text it shows it LTR even though we selected RTL in the Formatting tab of the textbox component.
There is not error to mention as this is a visual bug. I would like to add that the standard text component is working well for short sentences but when the text is long and has multiple lines the lines are displayed from bottom to top which is another bug.
Thanks,
Rani
