Dear @Nurullo
Thank you for your reply. I’ve understood the reason now.
I have another question about the mobile editor UI. Could you help me with it?
The toolbar header color when editing on iPhone and Android is different.
I tested this on OnlyOffice Document Server Developer Edition version 9.1.
Is there any setting to make them display the same?
I’ve described the detailed question in the post below.
Thank you.
