Changes made in Numbers not being saved on iPad.
For a while, I thought I was the one with the problem. Periodically I make changes and updates to various spreadsheets in Numbers on my iPad (3) and often when I reopen a file, the changes no longer exist. In some cases entire sections that I have deleted re-appear. Other times, new data that I entered no longer appears. This has been happening not only on the current iOS7 (7.1.2) but in the two prior releases as well. Since probably 90-98% of people will make a financial decision based on their spreadsheet, whether it is for budget, savings, investments, etc, this could be very damaging. I will now have to go back to using MS Office, as Numbers, which I otherwise like, can not be trusted. Further, I do not believe I'm the only one that has this problem, and I'm also certain that Apple knows about it. I am requesting comments and feedback. For some reason (memory management) an old image is being retained and displayed, or the changed file was never stored.
Thanks
