Nothing wrong with devices network connection but still Realms disconnects often and world is rollback, if this can't be fixed then increase autosave/backup frequency, or give an option to do so.
I keep loosing a lot of gametime due to this.

Thank you for your report!
However, this issue is Invalid for the bug tracker.
When everyone gets disconnected from a realm it generally means the server has crashed Crashes such as these are logged automatically by the game or realm server and investigated further by the development team internally, so they are not generally kept on the bug tracker.
If you can provide a list of steps that someone else can follow to reproduce a crash then feel free to create a new report. Please be sure to always search for duplicates before creating any new report. Please see the Bug Tracker Guidelines for more information.
Sometimes when a crash occurs the world will revert to a previous saved state. This specific issue is tracked as MCPE-12347.
