Update:
Our investigation has shown that what initially appeared to be a single problem in fact had two separate causes. Both occur only in the Android app and only for patients enrolled in more than one programme at the same time; neither occurs on iPhone.
Importantly, no data has been lost. Every measurement was recorded - in a small number of cases it was simply filed under the wrong programme belonging to the same patient.
The first pattern involves scheduled measurements and is very rare, affecting a small number of patients. The second pattern involves separate, self-added measurements and affects a somewhat larger but still limited group of patients.
We have implemented a fix so the issue can no longer occur, and we are making additional improvements in the next app release. If this issue has occurred within your organisation, Luscii will contact you about it.
