I don't know if this is the right place for this concern.
I am implementing a site with Moodle and I want students to be able to enter from the official moodle app, so far so good.
What I want to understand is if I can customize the Moodle app with the CSS file mentioned in the Mobile appearance (mobilecssurl) section? I have tried to do this by placing the file in my current topic and adding the path (URL) in the indicated field (mobilecssurl) but I have not been successful.
I do not know if in order to make any adjustment of styles I must compulsorily purchase or register in a payment plan? or I can do it with the file and I am doing something wrong in the configuration.
Thanks for your time and a thousand apologies if this query is out of the general context.
