I'm trying to quote some stuff from the Lightning docu using my mobile device (android, chrome) to answer questions on SFSE.
Update: this issue seems not to exist in iOS
As an unfortunate longpress doesn't allow to mark text. So copy+paste is impossible. Kind of show stopper sometimes and no fun.
I couldn't see a Desktop version link. Is there any? Or a different url?
If not, please Salesforce, change it. This is really an usability handicap.
