Decryption fails running iOS 14.2

[JohnK2]

Just updated iPhone and iPad to iOS 14.2. Now, trying to open an encrypted file, it tell me "Decryption Failed. Null" If I open with Excel, it works fine. Anyone else having this issue?

Hi @JohnK2, thanks for posting!

Could you send me a screenshot of the error that you're getting?

Also, what are the exact steps you're taking when you get this error? 

When you mentioned opening the file through Excel, was this by opening the file through the Files app, or after exporting the file from Dropbox?

Keep me posted!

Also, on my iPhone, I open dropbox and go to that combo file. Enter my password and get the result above. If i click on the "open" button, then I am able to open in Excel with my password. Never had to do this before my iOS upgrade yesterday. My wife's phone has the exact same issue. We are able to open on our macs but not our iPads or iPhones.

I am also having this exact same issue/same error message after upgrading to iOS 14.2 yesterday.

Glad to see I'm not the only one!

Thanks for mentioning iOS 14.2! I didn’t realize until you mentioned it that that was what changed to cause all my password protected files (excel/word) to no longer open within dropbox. I couldn’t find anyone else having this issue when I googled online for a fix. Thank you for posting it!

Me too. Just installed 14.2 but it happens when opening excel file from email so not just dropbox

Same here with a word document. Strange though, as I have 2 encrypted docs on Dropbox... one opens, the other doesn’t.

Same problem here! Cannot open MsOffice files protected with password, same error message DECRYPTION FAILED (NULL) after installing ios14.2...Please fix it. Thank you!
