I installed an update for Pocket Inventory and now I am not able to check in my device properly.
When installing an update to Pocket Inventory you should make sure that device is checked-in. Any data on the device that exists when an upgrade is performed may become unusable. If you performed an update while the device was checked-out and you are not able to check it back in, you must click on manage device and clear the device so that you may check it out again with new data.
