Hello @mitko25522, thanks for reaching out.

The swizzled function is called in the same thread the original call is made. Are you fetching this data also in the main thread?

Hello @brustolin, thank you for the quick reply and the information. There might be a case where we are fetching the data in the main thread. I will check.
