Arabic App Name Issue

YazeezNasrullah — Wed, 21 Jan 2026 18:09:01 GMT

I'm having a problem when the app name contains Arabic letters, and I can't change it to just English letters; it has to contain both Arabic and English letters.

Is there a solution to this problem?

The above is the only real solution at this time. It may be feasible to offer a means to only customize the app name - rather than needing to set/override the entire user-agent, if this is something that may be useful. We'd also be interested for any other users to comment on this thread if this is a limitation you face.
