When you are using both Web client and Android app changes in Web client are not making it fast to the Android app. You have to manually force sync on Android app to see changes.
Hi @anon9083433 
Sorry to hear you are experiencing this issue! Can you try reinstalling the app and let me know if the issue persists?
Thank you @anon9083433!
I switched to Asana Beta app and it’s still the same: any changes I do in the app are immediately visible in the web version. But when I’m opening project or ticket in the Android app no changes done in web version are immediately visible in the app. However if I open the changed task it will be synced. All other tasks in the project are not.
