Software was originally maintained in bitbucket. Bug reports were recorded in BitBucket's issue tracker. As of early 2020, the app engine software is maintained in GitLab. EF and iOS code are maintained at github.umn.edu.

===UNRESOLVED===
====Time Travel Error====
In UserStatus, some participants' "last location" dates are in the future (i.e. the date of last location logged is a date that has not happened yet). This appears to have affected participants who enrolled in November 2017.

====Android Location====
Several participants with Android devices do not have current location showing, even though they have it turned "on" in their phone settings.

A new Android app was released on October 27, 2020 with improved location tracking for participants.

===RESOLVED===
The following document details software and bug reports about the CoTwins app and servers which have been resolved over the duration of the study. This document is meant to serve as both a log of the reports and a reference for resolving any future software or bug errors of like-manner.
