Lost work made with 'Fill and Sign' in Acrobat Reader DC (saved work before exit)

I spent HOURS on Sunday working on a Fill & Sign document. I came back this evening to finish it, and the PDF is now toally blank. Paying for this Adobe Pro and using it on the web is not worth it. It's so clunky and non-intuitive to use. Now, it has lost a half day of work on my day off. I have to start over, and it's due tomorrow. It's going to be a very late night. Thanks, Adobe. It's definitely time for me to cancel this monthly service and use Word or Google Docs. I do not see a viable fix on this. I used the web-based version on a Chromebook. 

I dont know if this issue went away then returned or if it just never went away. I 'm experiencing this issue too. I fill out pages full of info with fill and sign, saving my progress with each entry, then randomly when I save an entry it will deleat all the info I previously added, undo will not restor the info because it deletes only when I click save, so the file gets saved with all data removed. So much productivity is lost with this issue. what is the fix for this? 

Well, it's been a few years since this thread was active but I'm having the exact same problem. I've been a Creative Cloud subscriber for about 5 years and haven't had the problem until this week. It seems to work perfectly as long as I only fill a pdf, but if I sign one, the signature and any data I added during that session will all be gone when I next open the file. Sometimes, after redoing my work and saving it over again, and again, and again, it will suddenly work but that's obviously extremely frustrating and not a real solution.

I have tried making copies of my files, restarting my computer, and un/reinstalling Acrobat but all to no avail.

My situation is a little different but if it helps anyone, great. We send out contracts/forms to be completed by our customers and sent back. They "save as" so it reflects their account with us. It seems that when someone is using a mac, or really any Apple product including an iphone, even though they have saved the completed form, it comes back to me blank when I open it in MS Outlook which in turn opens the document in Adobe Acrobat DC. But I just discovered that if I use webmail (like gmail), when the file is downloaded and opens up in my browser, all the info is there.

It's not a fix, but I hope some of you can find your info if this applies to you

I have almost the same issue using a standard fillable field  such as an IRS form. Using a MAC, I filled in the form just as I've done in past years, and saved it. When I opened the file a few days later, nothing came up, but the file size indicates that there is data. To confirm that, I clicked on a field and the data showed up in that field only!  However when I released the click, the data was gone.

This was hours of work on multiple forms.  Adobe, where are you ??????

Has this been resolved?  I am having the same problem.

What a fiasco, Adobe. Hey wasn't the whole forced down our throats Creative Cloud subscription model so that Adobe could release continuous updates and features? Oh wait, maybe losing all your work IS a feature!

I am glad I'm only losing a few sections of one page of a fillable form.

Here's a workaround if you only have one page: export it as a jpg.

The android app has the same issue.

Anyone with some free time, please call adobe helpcenter to complain.

I've come across a solution. According to some other forums relating to the same issue, it seems as if disabling Javascript in the Adobe Acrobat settings allows you to save and open fillable form documents with your entries. Save your filled form with a NEW FILE NAME than that of the original. The file will preview and open with your forms filled in both Adobe Acrobat and Apple Preview. After you're done with signing your files, remember to enable Javascript again.

Same f-ed up situation. Lost everything except for few random phrases.. Now... how the hell those few phrases were saved ad the rest of the comments are gone??? Did everything that was advised in the comments above and nothing helped. Any help, Adobe Support???
