Cant write in Hebrew in "fill & sign"

Hi there 
 
Hope you are doing well and sorry for the delay
 
What is the version of the Acrobat DC you are using? To check the version go to Help > About Acrobat and make sure you have the recent version 24.01.20604 installed. Go to Help > Check for updates and reboot the computer once.

Also check the help page: https://adobe.ly/3VoTOVD and see if that works.

Let us know how it goes.
