Your onX account is currently limited to 1,500 Markups (Waypoints, Lines, Shapes and Tracks) in order to maintain a high level of responsiveness and functionality. This is a limit on your account, so if you have Memberships for more than one onX App (Hunt, Offroad, and Backcountry), you will be limited to 1,500 Markups across all three Apps.
There are a few strategies you can use to avoid running into problems with the Markup limit:
Hide Markups: If there are markups you do not regularly use, we recommend hiding them by unselecting them in the My Content Menu. Hiding a Markup will remove it from the display, but you can show it again at anytime.
Delete unneeded Markups: If there are markups you don't need any more, we recommend deleting them completely from your account. Tap the three dots in the My Content Menu next to the Markup you want to delete, then tap "Delete" in the Options Menu.

Export and store: If you don't plan on using a set of Markups anytime soon, but don't want to lose them forever, you can use the Export function in Web Map to store them on the computer as a KML or GPX file.
Please be aware that KML and GPX files do not support onX colors and icons, so only the position and name associated with a Markup will be saved in the exported file.
Exported Markups can be restored (except for the colors and icons) using the Import feature. Click here for more info about Importing and Exporting Markups.
