SnowieApp only supports NL Hold'em cash games. Please make sure that such hands are showing in your active HM2 database.
SnowieApp will automatically attempt to import hands from your HM2 database every 5 minutes.
If after 5 minutes hands from your HM2 database don't show inside SnowieApp, please follow these steps:
1) Open HM2, go to Settings > Featured Logging and enable the HMApps option and increase number of saved log files to 10. Click OK and restart HM2.
2) After restart go to SnowieApp tab and click Resend hands button. Please wait 10 minutes to let SnowieApp attempt to analyze the hands.
3) If hands will not show up after 10 minutes, close your HM2 and submit the log files - Hold'Em Manager 2 FAQs - Poker Software :: How Do I Send a Log File to Holdem Manager Support?
4) If hands show up you can disable logging that was enabled in Step 1.
