Additional information. I open in web app Completed task page - this task was here. Then I open Today task page and task disappeared.

Hello,

Did you refresh the web page after the sync on Android successfully completed (the sync button stopped rotating)? Did you refresh the whole webpage or just click on the "Reload the tasks list" at the bottom of the left-side menu?

And does it still happen now?

Sorry for any inconvenience.

Hello.
Yes, refresh whole page several times. But task was left on the page.
When I open "Completed task" page in the web, this task has been there.
After this I again open "Today task" page and this task was no more.

I got it again to reproduce the problem. In android I make complete task in the Today page. Then click on the "Reload the tasks list" button (sync button long time rotating). After his stopped rotating I click refresh button on the web-browser and task still on the page. Then I click "reload the task list" button on android (button quickly stop rotating), and after I refresh web page the task is gone away.

I think, synchronisation was not completed, but I cannot see this on android device.

Please do as below to have a try:

1. On the Android app, add a new task in Today box and meanwhile, complete another existing task.
2. Tap on the sync icon at the bottom right corner.
3. After the sync icon on the Android app stops rotating, go to the web version, and refresh the whole webpage.

Now, check if the newly-added task is showed in Today box on the webpage. If it is showed, please check if the completed task disappears from Today box.

And then, 1. please complete a task on the web version; 2. tap on the sync icon on the Android app and check if it will disappear from the list and go to the Completed box on Android app.

Ok.
After first part - completed task continues to appear in the web.

Then i add task on the web page, click sync on adnroid and task was displayed on android device.

After part two - completed task was displayed in the Completed box on Android.

I make another test. Click on Completed tab on the Web App, the completed task on first part was there. Then I click on the Today tab on the Web App and task disappeared.

Please now add a test task on Android app and tell us the task title.
Then complete the test task and make a record of the time when you check it as a completed task.
Lastly, tap on the sync icon on the Android app and also tell us the time when you tap on the sync icon.

And we will check the log and see if there is something on the Android app ASAP.

Hm. Now it is work OK. I try add and close several task

Please don't hesitate to contact us if it happens again.

Thank you for your feedback and support.
