Devices loose settings

[Doni_Nvrro]

I’m experiencing some problems with settings configuration.
My apps requires Google account in white list to connect.
In the settings configuration i save information like year to work, counter, adress to send emails, and some information to automatize work user.
Many devices, i don’t know when and how, loose data settings and the reports, workflows and slices in the app don’t work.
I’m experiencing this problem with Android and iOS devices and can’t find whats happening.

Thanks for your help
