*Edit: issues were fixed in Ae 2023 and work fine. Thanks!
Here are the issues ranked from the most severe to an inconvenience:
1. Range selector animation does not work properly for Hebrew Text:
the animation is reversed, for one line you could hack it with setting animation to "start" instead of "end" and reversing the keyframes. with 2 lines you are doomed.

2. Highlighting/Selecting Text problems:
this happens when you have combined text of Hebrew and English or Hebrew and numbers in the same layer or Hebrew with another Hebrew that has a change in size or weight. the situation get's worse when you move the layer, the selected area of the text is changing making it hard to select anything outside the Hebrew letters

Moving the text makes it worse:

3. Wrong translation for "Sample" in the Font Preview:
the preview for Hebrew fonts is written "לטעום" which is a bad attempt to write something like "Sample" but in hebrew it means "to Sample" aka to taste something. it should be "דוגמה" which is "Sample" or "Example"

4. Adobe Clean looks bad for Hebrew:
the letters stick to the top when on layers, and are pretty ugly in general 😞

General Feedback: I really thing the MENA implementation in Ae should be seamless same as Ps and Ai. you should not have to choose between engines. many times you are combining both and I hope it's a temporary phase until the MENA engine will be stable. the current setup is not that bad because you can combine in the same project both of the engines, but have to change each time. restarting the software is not required which is a good thing. this way I could use MENA engine for things that work and not use it when things that do not work. hopefully in the end it will work for everything so I won't need to select it and simply enjoy typing freely in both languages.
Thanks!
