Hello. This must be a very crazy question, but I have to ask.
One of my external testers repeatedly reports that right after installation of my app on his iPad mini (on top of the previously installed version) and using it for a couple of hours, the memory usage (storage) increases significantly (by about a Gig). When he completely removes the application and re-installs it, the storage seems to be back to normal. Besides, there is nothing in the code that could produce a leak of a Gig in a couple of hours. I am at a loss now whether this may be a problem of TestFlight. Has anyone ever experienced something like this?
