my question might lead to confusion so my idea of the process is:
1. Launch DLS21
2. Sign in to Facebook in DLS21
3. Go to Facebook Apps settings i.e. on PC
4. Remove DLS21 from Apps settings i.e. on PC
5. Check DLS21 app
Will this process cut the connection and simply remove saved data I am trying to retrieve from Facebook or will data be saved locally and overwrite the actual local saved data?
