Steps to reproduce
Using the customization CSS feature for pro users, I have defined custom CSS. The custom CSS works fine in all clients (Browser, desktop, and mobile).
I expect the custom CSS to be available offline in iOS (as it seems to do in the windows desktop version).
When offline, the custom CSS is not applied to outlines, defaulting back to the default CSS styling.
While this may seem subtle and not crucial, the Mobile applications slowly become more crucial to my daily work and good working parity between all environments is crucial.
I also want to mention I have been experimenting with the @import url command and it works well, except it doesn’t work offline in any client. I was hoping the clients might cache the remote CSS, it doesn’t. I can live without this, but I thought it was worth mentioning.
