Thank you for your post.
There have been no memory leaks reported based on your description.
For clarification, is the file local or hosted by FileMaker Server/Pro? If hosted, what version of FileMaker Server/Pro?
If you have an example file that demonstrates the slow performance, please send it in. I have sent you a private message with instructions where to send the file.
Thank You for Your answer!
the file is local on the iPad. On OSX, version of FileMaker is 15.02 (Advanced) - used for testing/checking
I can't send the file, it's too big and contains private customer data. Will try to create a clone, but that won't be possible shortly
