5-star reviews?? Loses data if phone rings – myOffice - Microsoft Office Edition, Office Viewer, Word Processor and PDF Maker Review

This is the second time I've written this review because the phone wanted my App Store password the first time I tried to send it and it didn't go through and the review disappeared so I am not a happy camper. I wonder if any of these 5-star reviewers have actually used this app. It took all of an incoming phone call to lose half an hour's work yesterday. I answered the call and when I went back to the app it opened (reverted) to the default page instead of to the document I was working on. I lost half an hour's hard work. I hoped the backup copy would contain the missing text, but no luck. It was a backup of the last saved copy. The app did not do a save before closing the doc. I thought maybe I screwed up but it happened again when I called my cell from my landline. It also happens if you leave the app to check your mail or answer a text or use safari. What kind of 5-star program is this? Also, they placed the delete key right below the edit key (which opens your doc) and guess what happens if you hit the skinny delete button instead of open? Luckily the file was sent to the recycle bin instead of actually deleted, and there is a backup copy anyway, but come on... For those of you expecting to work in an actual .doc file that doesn't happen. You can download and read a .doc file, but to work with it you first have to save the file in HTML format in word, upload it to Dropbox or Box or whatever, and download it into the app. The app can't convert the .doc file to HTML itself. Once in the HTML file the app worked as advertised, until the phone rang. This is not a 5-star app. If I am doing something stupidly wrong or someone out there knows a workaround for this data loss problem, please note it in a review and post it so the rest of us can safely use this app. As it is, I don't dare use it without doing a manual save every five minutes.
