Why is the app no longer available in the App Store?
TT has had some management and development staff issues of late. The new management has been scrambling to find and train development resources. The apps had not been updated in quite a long time and with changes to the requirements for posted apps they are automatically removed if they don’t meet the new requirements.
I have however been suggesting for a long time to stop using the App and just access TT from your mobile browser. It literlly looks the same, gives you normal browser back and reload options and allows you to RSVP and use the Checkout function for an event with payment. The event with payment RSVP Check out not working in the mobile app was reason enough for me to tell everyone in my unit to stop using the app and access TT through browser on whatever device they have.
