Help for General Hub Problems

(Low memory, errors, crashing, hub becomes unavailable, etc..)
The VERY FIRST THING to try would be a Backup and Restore (this automatically performs a Soft Reset in the process). This will clear out any database issues from an improper shut-down or other system issues.

• Go to Settings > Backup and Restore
• Take a local backup and download it.
• Immediately Restore the backup.
