You need first to install an old version of iTunes on your Mac (version 12.6.4 is the latest one that deals with apps installation) https://secure-appldnld.apple.com/itunes12/091-60759-201803029-1F70CB08-3131-11E8-9791-31052B2AA206/...
then on your Mac you open the folder /Mobile apps within the /Music/iTunes library folder and search for excel.ipa file
you open your backup disk and search for an older version of this excel.ipa file and replace the newer one
then you suppress Excel on your iPhone/iPad
then you plug your iPhone or iPad with the lightning/usb cable to your Mac and after selecting your iPhone within iTunes, in the app section you drag Excel to your iPhone. That will install the "old" version of excel on your iphone
Hope you can help me. Yesterday all worked perfectly.
Today Im having trouble getting into my dropbox from the word app (all office) on my ipad. I can get straight into my files on the dropbox app but cannot open them in word, edit them or access any dropbox file through any office ios app.
Please help! This has been driving me crazy.
I have a temporary workround for reading dropbox Excel files from my iPhone.
Click "Open" (file symbol) at the bottom of Excel. This takes you to Places. Click "... More". Click "Browse" (file symbol) at the bottom of the page. This takes you to a list of recent files which you can download and open. You can autosave but cannot save a copy as you get the "Cannot Open Folder on Server" error message.
