cTrader Mobile cannot connect after 4.7 update

I would like to report and ask for help to the cTrader team, especially cTrader mobile. After I updated cTrader mobile to version 4.7, my cTrader cannot connect as usual, and only spins around (connecting...) This happens on cTrader android/iOS. and on older versions of cTrader it can still be accessed as usual. Please fix this connection problem, this is very disturbing to our trading, I live in Indonesia. I have tried all the internet providers available, but the results are the same.
Thank You

Version 4.7 & Old version
