Problems with Nozbe Mobile application

I still am having problems with the mobile application (used with Opera Browser in Windows Mobile 6.1). Last night I created a new activity on the web and updated it and all appeared to work OK. No messages of problems or errors. But after I updated it, it did not show up in the list of actions for that project and this morning when I opened Nozbe on my computer, it was not there either. What happens to new stuff I create on my smartphone? Does it go into the ether? I need to know if I can depend on this or not.
