When I collect more than 20 trees I can’t see the first trees.

When I collect more than 20 trees and then try to scroll to the top of the tree list to view the first few trees, they are gone. I know the trees are being saved because when I upload them I can see them in InventoryManager and in ArcGIS Online, but when I reopen the tree list for that plot I can’t display the first trees.

Most likely this is because you had collected more than 20 trees.  There is a setting in MobileMap to optionally limit the amount of trees that are displayed.  The default is 20, which works well for typical scenarios because a typical BAF plot will have 5-10 trees for most foresters, while a 100% Tally will not get bogged down trying to handle scrolling of potentially hundreds of trees.  To fix this, change the max tree rows to display setting near the bottom of the Trees settings (Settings > MobileMap Cruise > Trees > Maximum Number of Tree Rows.

MobileMap Freezes With Message "backing up database" After Closing Tree List

When closing the tree list MobileMap freezes with message "backing up database" and a spinning circle. I have to force close the app and restart. No data is lost, but once the problem starts happening it seems to happen all the time. Uploading my data seems to help for a while.

This is typically caused by insufficient disk space.  MobileMap tries to make a backup of all features that have been created or edited since your last upload.  After a big data collection, the backup file can be large.  After many days of collection, there can be a large number of files.  Since your device had limited space when we set it up on Monday, this is likely the cause.  Deleting files to free up space should resolve this issue. As a workaround you can disable the automated backup in settings (Settings > MobileMap Cruise > General > Database Backup Interval) by setting it to ‘Never’ but this is not recommended as it could put your data at risk if your device is damaged prior to backup.
