PokerTracker

After the update, it no longer will self-update the running list of hands, nor does it show any active table stats. If I refresh the today's hands tab then they show up, so it is reading hands.

If you are playing at Ignition, WPN, GGPoker or a couple of other sites that is a known issue in PokerTracker v4.18.
These hands are importing with an incorrect time and this can impact if hands are displayed when a report is based on a specific time period such as the 'Play Poker' section however the hands will be visible in 'View Stats'. If you open a Support Ticket we can notify you when a fix is available and in the meantime you can revert to PokerTracker v4.17.15 here (unless you have also updated PostgreSQL beyond v12) where new hands will import with the correct time again. Unfortunately this will not fix hands that have already been imported - they will need to be purged from the database and reimported.
