it's 2023 already, how many existing Arab teams are forced to use the English interface?
and how many teams are waiting for the Arabic interface to join in?

Are there any background studies being done regarding this?

the Arabic community is huge, why is it being void till now? the interface is so easy to translate and just announcing the need for volunteer translators for Arabic you will find a huge response, the lack of support tickets doesn't mean a lack of interest a proper study should have been made
