Arabic Layout has too many buttons for smartphones
Arabic layout has too many buttons for smartphones, but it seems suitable for tablets, as i is almost identical to real physical Arabic keyboard, which makes sense, but buttons gets too crowded, small, hard to type,inaccurate and slow to type.
You can easily add another layout with one less character in each line, and make it as another Arabic layout, like name it "Smartphone Arabic" and he original one "Tablet Arabic"
Spear your breath brother seems Swiftkey don't and never care about this big problem in whole Arabic layout on the keyboard, see link below make this feedback months ago about same issue u face but they claim should all Arabic user share or reports this! And then maybe they will think to do something to fix

The problem described in your link is different.
Anyhow I did notice the total failure of the Swiftkey team to even answer and care for tye problem, in comparison to "A I Type keyboard" support, who even had an Arabic speaking support person to answer me un Arabic language and kept the connection till I solved my issue. So I gueas I will stick with "A I Type Keyboard" it does present useful other features like copy, paste, select all, cut, undi, redo, arrows, and all integrated into empty letters, and it does solve both my issue and your issue, I do recommend you try that
It's same problem because the Arabic layout in Swiftkey not the standard like the one in Gboard or ai type keyboard so they add more buttons which lead to decrease the size of them.anyway since shared the problem in my link I turn it to use gboard it's more reliable for Arabic users. Good luck🍀🤞
