Data upload issue when network connection is off for long: Issue on iOS app

[devhci]

If the network is off for the long time (e.g 10-12 hrs) and when too much data get accumulated locally on phone from passive sensing, iOS app starts crashing when the internet is turned on. If the internet is turned off app again starts behaving normally.

Tested on iOS 16.6
Model : iPhone SE

This issue exists only on iOS APP. Android app works as it should.

The app probably tries to load in too much data into the memory to send, which may be a problem on older devices like the iPhone SE with 2 to 3 GB of memory

I did several tests with an iPhone SE and the latest App version after the memory improvements by manually stopping data transfer (network off) while capturing data from the Accelerator and/or Polar Verity for several hours. The transfer of the collected data from the mobile device resumed without loosing datapoints or crashing the application.
