Has something changed recently with the CookieContainer class - particularly perhaps in relation to serialization.
Our app uses CookieContainer to store cookies and persists them across sessions using binary serialization. This has been working flawlessly for probably a couple of years. Last week we started to notice occasional crashes related to CookieContainer - either while deserializing or accessing the contained cookies. These crashes seem to happen when upgrading older versions of the app to the lastest (as opposed to fresh installs). The crashes happen on both iOS and Android. Uninstalling and reinstalling the app fixes the problem, but this isn't a viable solution for our customers.
