Fix ionic 1 app that loses local storage data expecially under iOS

Hello, add "STOGARE" to your bid. No automatic bidding here. I have an Ionic 1 App where I need to make some fixes. The App has a reserved area and user login information, as well as any other information it is stored in the localStorage. Unfortunately it happens that expecially under iOS and in some devices, apparently the information in localStorage gets lost, so the user has to repeat the login process every time he/she wants to use the App. This is very very frustrating. Currently I could not reproduce the problem, nor fix it obviously. I need someone that has one or more iOS devices that can make some test, check the code and try to figure why this is happening. Some idea about what could be happening: -Device with low memory (ios cleans some data randomly) -App that gets killed somehow brutally loses its data -Some BUG in the app I'm aware that you could work on the App without solving the problem, you'll get paid anyway if you tell me all the test and work done.
