Thanks for your reply!
This has been identified as an improvement which will be added in release 4.0.1, currently customer is using SDK 3.6.1.
If release new SDK 4.0.1 to customer, this could be a big problem to them because we need:
1, provide the simplified new SDK file, because App size is a concern;
2, customer will ask a meeting to review the code;
3, function test in UAT and then PRD system;
I want to know if this defect can be fixed by certain parameter, configuration or hot fix on top of version 3.6.1? Thanks!
