Get back to your auction.
An older installed app can hold on to a screen that has changed. Check for the latest version, then open the demos or return to your event.
Save any work and finish bidding in other OutbidX tabs before restarting them. Checking for an update does not clear your data or submit bids or payments.
If the update stays waiting, finish and save your work, close your other OutbidX tabs and reopen the site. Do not restart during an uncertain bid or payment. No cache deletion is required.
