New Update is Alright

I like the new look of the app it’s better than it was previously.

Not working correctly!

About 2 months ago this app stopped working properly on my iPhone and iPad. I cannot scroll down to see the full schedule and when I switch to another day, it freezes and gets stuck so I have to close the app and then reopen it again to view another day. I’ve tried uninstalling and reinstalling, changing my password and also shutting down my phone, leaving it off for 10 minutes, then turning on, and problems continue. Was told an update was coming but have not seen it yet.

Never not bugging

This app stays freezing. If you try to skip more than a week ahead at a time it freezes. New update means if you drop a shift you can’t undrop it/see if someone picked it up unless you open it on your computer.

Weeks of Not Working

It has been several weeks since the app last worked properly. i have to exit out of the app every time i go to check the full schedule, as the entire app just freezes after it is pulled up.

Keeps getting stuck.

I go to view the full schedule and the app seems to get stuck and I can’t do anything. I have to close the app and open again if I want to see something else. It was working great up until about 2 weeks ago. I’ve tried logging off, changing password, uninstalling and reinstalling app, clearing the cache but nothing seems to work.
