Sync issues between iphone and cloud and desktop/laptops

Both and it basically occurs each time I do this. Most recently today when I created a new account and password within the browser app, then went to look it up in the standalone app. it wasn't there. So I circled back to my iphone app and it wasn't there either. An hour later it had been updated but I wasn't on this task anymore....so I punted it til I get back to this issue....but it's frustrating as hell when I'm trying to accomplish a given task and then am distracted into a problem solving/easter egg hunt for the data I just entered minutes before....to enable myself to function more smoothly! It's made me more frustrated, less efficient, etc.
I am tempted to just recreate a spreadsheet flat file.....honestly. Feels like all these tools have gotten less handy and more high maintenance when they are supposed to HELP not add to the burden.
