I think this is an issue with Thunkable x. It is about the different device language.
I test my app on two phones (Note 5)
One of them has Arabic language and the other has English language.
Look at these two pictures from Note 5 with Arabic lang system and Note 5 with English lang system.
Sorry what’s the problem? I’m not able to tell.
In the device with Arabic language system, The yellow line under tabs never moves and the direction of components is changed from left to right. Also the direction of tabs is changed as well.
That’s because (I actually don’t know I’m just guessing) Arabic is right to left and so the phone just reverses everything no matter what it is
