All sections have a limit on the amount of content which will display inside of the app. The Locations service is limited to 250 entries due to limitations of the maps in Mobile Roadie apps.
Displaying Locations Section Content in Addition to the 250 Entry Limit
If more than 250 Locations are needing to be displayed inside of the app, content will need to be organized and assigned to Categories (currently only available on Pro Accounts).
Note Each category has the same content limit as the Section whose content is assigned within that category. Categories in the Locations Section have the same 250 Location entries limit. There is no limit at this time on the number of Categories which can be created with 250 entries or less.
More information on Categories and how to assign content can be found here!
