I have stupid, but very unpleasant trouble. Yesterday morning I typed about 40 pages in MS Word on my iPad Air, I saved my document, that's all. This morning I've demonstrated my work to my chief, but 10 or 15 pages had disappeared. During some hours, I stacked in bad position among my article and my boss. What can be the sequence of my actions?

saved as pdf. sometimes it gone even in android/ios.

those pages are not actually "gone" as far as my experiences go. it's just that on mobile devices, the formatting/view makes it very different compared to pc, with the pc being the "true" view. so everytime you edit on mobile, make sure to check back when copied to pc. else, save as pdf when done. pdf would show the same on both mobile devices and pc

I don't have enough experience in searching for solutions or articles on the Internet. But I had to use some search engines like Google, Yahoo and Bing and what I dug up there... https://onlinefile.repair/en/word.html - as I found out from contacts of this resource, group of programmers created it, but I'm afraid of doing it immediately, because it is new thing for me. What opinion do you have about this masterpiece? Can I use it for my case? If someone applied it, share your thoughts how it works and how much it might be effective.

Unfortunately, I didn't find any resolutions from Microsoft - I can't realize why such huge corporation doesn't care about safety of data of their customers like me, like you. This question for me now doesn't have an answer. If someone owns this information, inform me, please.

I wasted several valuable hours of my spare time and I've no idea who or what could return me these very hours. Pats, I hope this time or next time you'll be more sympathetic to problems of strangers on your community.
