app stop reponse when I select the org at ort tree lower level when the element is a org type in android tracker. for example, slowly at level 3(>500 orgs) ,dead at level 4 (just one org)
Please follow @Gassim advice and let us know more details. And eventually report it in JIRA with full details of your specific device, program and OU structure.
I have created an OU at level 2 with 1000 OU at level 3 and I don’t experience the issue.
