The TextBox property ClearTextOnFocus no longer works as intended. When a TextBox gains focus, it’s supposed to ‘clear’ the placeholder text. Right now, this is not the case; instead, you must type in the TextBox first.
As you can see, the placeholder text stays visible on initial focus. This might confuse players.
This was a deliberate change we made. Placeholder text now shows when the textbox is empty, instead of only when the textbox is both empty and unfocused. This brings us in line with other apps on your PC which usually do this as well.
The placeholder text is not cleared by this property. All the property does is set Text to “” when the textbox becomes focused.
Since your placeholder text and text are the same color, one way you could work around this would be to leave the placeholder text empty and set the text to “[Twitter Code]” instead.
