I hope you are well today. Sorry for taking long to get back to you - I would recommend you upgrade and use DHIS2 Version 2.32 upwards. Kindly remember to run the scripts for each version as you upgrade (2.30, 2.31, 2.32)
FYI, We tried to upgrade to 2.32 but failed. But we succeeded upto 2.31. Hence, currently we are focusing to use 2.31. Also we are trying the Tracker App version 1.3.2. Things are going smooth so far.
