After putting the app in the background and turning off the screen for a few seconds, it is not possible to write files again.

Open app on IOS (real device)
Download some file and save it (write_blob(...))

What happens if you change this line to true? https://github.com/diachedelic/capacitor-blob-writer/blob/cb517d6c82920f90226ec07b6ddf6dfebc5c8f9d/ios/Plugin/Plugin.swift#L77

It's working!

I set that option to false to fix #49. What version of iOS are you using?

diachedelic commented 2 years ago

This should be fixed in v1.1.4, please test.

This should be fixed in v1.1.4, please test.

I am using iOS version 15.6.1.

Now it works fine with version v1.1.4.

Thanks!!
