What have you done? This app performed perfectly for me with by Zwift trainer and today I opened it and it completely changed. The interface is different and doesn't work. I choose 45 minute workouts and it switches to 60 on its own. I start a workout and it doesn't make it one minute before it crashes. I rebooted, I restarted. Four crashes and I give up. It's absolutely trash now, Please revert to the old app until you can make this one work reliably.

Sorry, Android 15 required a lot of changes that we finally did them and it is causing some users issues. We are working through every issue we can find. For most users it is now working fine. It might be a few more days before we can address every device issue that is included. Contact me at support@trainerday.com and I can help.

it's not what I thought and the app is very difficult to use. it's almost impossible to use and keep straight, day to day, what you're trying to do. I used it for 2.5 weeks. I tried to get a refund. I thought I purchased this through the site but it wound through play store. trainerday has been no help. I cannot suggest this. edit: I contacted play store and they would not help me with a refund. trainerday will not help. this is in reference to trainerday reply.

Hi sorry you feel this way. As I mentioned in the email if you contact the play store they will help you with a refund. I would be more than happy to help you with your app struggles. We have a lot of features and that can increase the learning curve.

If you contact support@trainerday.com I can help you more, but I tested with Pixel 9 Pro and have no issues, it must be a specific device or something with your account.
