Update: Try uninstalling and reinstalling the app if you are having problems after the 1.94 update. I had been thoroughly enjoying this app despite its premium price up until it forced me to update to version 1.94 today. This new version is doing something funny with memory so I get a warning every minute or two that my system is low on memory and I need to close other running apps. Pro-tip: there arent any other apps running Shark Bridge. You are the problem. The supposed bidding engine updates also are questionable. Ive always been annoyed that multiple people bidding the exact same hand get different results, but that seems much worse now. The few hands that I soldiered through despite the above-mentioned warnings were complete chaos. Hopefully, we will see a better update soon.
