Note: if you are already using 2.31.0!
There is an addition manual upgrade action required if upgrading from 2.31.0 to 2.31.1 (please check the Upgrade notes link below!).
I just tested in demo and is working fine. I would suggest you check with your DHIS2 admins and ask for support in the main channel, as this is a thread for the Android app and will not get much attention.
Sorry for the delay in replying - we are currently preparing the next patch, 2.31.2, for release!
Do you still have the issue? I can ask our tracker experts to take a look, but first, can you please give some detail on exactly what you have tried and the results?
Have you searched for similar issues on this community and ruled out common problems such as clearing the cache?
Please note that, as Marta indicated, the sort of issue you are having is best raised in the Support channel - people don’t tend to to follow comments on an Announcement so actively!
But you can always send me a direct message if you feel you are not getting timely support.
