Disconnection timeout while in the background

Hello,

when switching applications on android mobile using cTrader cross broker app the connection gets lost after 60 seconds, then when switching back it takes a few seconds to reconnect. This is sometimes annoying when for example I'm reading news or checking something in the browser and I do want quickly get back to the chart action.

All the relevant settings in android to allow background data and even exclude the app from battery optimization are set, so it looks more of a intentional design than android killing the connection. Is that correct? Could the disconnection timeout be set to be configurable?

Thank you!
