This works, if I turn off my internet connection, the next portfolio requests show the old balance.

However the first portfolio request after losing connectivity seems to take a very long time to resolve (~1.3mins).

This is a big issue due to the fact that marketmaker is single threaded so it completely blocks everything and makes the app unusable for over a minute.

It could possibly be caused by losing network while a request is happening.

Is this just due to an internal timeout? If so do you think you could decrease it?

This issue is resolved so I'll close it, will open a new issues regarding blocking the main thread.
