@tharwi Thank you for reporting. We need to run a profiler on the app to see how the two different versions behave.

Hi @kneth, thanks for looking into this. I’ll wait for any updates or findings from the profiling. Please let me know if you need any additional information from my-end.

Hello @kneth and team, any update on this?

@kneth is no longer an active contributor to the project. With the notice of deprecation it is unlikely that this issue will be resolved any time soon (if at all).
