Unfortunately the Betfair woes continue and so far the technical teams have failed to find the root cause/supply a fix.
As such, lots of messages are timing out (i.e. receiving no response). Whilst this primarily affects the market loading/navigation, timeouts are occuring in other parts of the API as well.
I apologise for the inconvenience, but we are in the hands of Betfair whilst they investigate/fix the issue.
