So far, we do not support all browsers on the mobile phone.
For iOS: we just support tracking the history of the Safari browser only.
For Android: we support tracking the history of a default browser (Browser app), Chrome. Since Jan 2019, it supports UC Browser, Firefox as well as almost all browsers apps.
Please remember to turn Accessibility on to make this feature (URL browsing history) work: Normally, you will go to Settings>More settings>Accessibility>(System Service) and turn on the switch.
(System Service): It is an alias of the application (client/target version). Some versions of the application, maybe it is Internet Service, Backup Service, Auto backup Service ...
I hope that helps.
