I have a stable webapp running on a number of company iPads running iOS 8.0 and some on iPads running iOS 10. I had a user upgrade an iPad to iOS 11. The app uses a lot of memory (approx 200 MB) to store images as base64 strings in a webSQL table. In iOS 11, the app freezes after loading approximately 30 MB of the images. Has iOS 11 changed how it manages/allocates memory to webapps?
If this is indeed a new limitation, any ideas on how to get past it?
