Hi.
I’d appreciate any advice regarding the issue described below.
Steps to reproduce the problem:
- Access iCloud.com from Safari on my Mac mini using my account.
- Create and save a Numbers spreadsheet.
- Access iCloud.com from Safari on an iPhone SE (2nd generation) using the same Apple account.
- Tap the file icon of the saved Numbers spreadsheet.
- Safari navigates to “about:blank” and displays an error message.
- Error message:
**This spreadsheet is unavailable. The owner stopped sharing, or you do not have permission to open this spreadsheet. **
I used to be able to view these files, but now none of the spreadsheets will open.
Environment: Intel Mac mini (2018) macOS Sequoia 15.7.7 Safari 26.3 iPhone SE (2020) iOS 26.5 Beta 4
What I’ve tried:
- Suspecting a Safari issue, I installed Google Chrome on the iPhone and tried accessing iCloud.com, but encountered the same error.
- Installed the Numbers app on the iPhone and accessed the files on iCloud — they open successfully.
- Created and saved a new file using the Numbers app on the iPhone, then tried accessing it via Safari and Chrome through iCloud — the same error occurs.
Additional information: Other files on iCloud (such as Notes) can be opened across devices without any issues.
Installing the Numbers app on the iPhone allows me to view the files, but since I only need to view them (not edit or create new ones), I’d prefer not to install it if possible. This might be related to participating in the beta program (I’ve already submitted a report via Feedback Assistant). Would downgrading be advisable?
Hello @shigezhino,
At first, I asked my question on the Apple Support Community. However, I was advised to post it on developer.apple.com since my environment includes beta software,
I'm sorry to hear that. I know what that feels like and it's definitely not the intended experience.
It's important to note that beta software is not final and may introduce unexpected changes or issues.
The correct channel for reporting issues with beta software would most certainly be to file a Feedback Report through Feedback Assistant on the device, preferably, and if not through the website, in this case.
From the beta software page at developer.apple.com/support/beta-software/
Apple beta software, also referred to as a preview, seed, or release candidate, is for developers to take advantage of the latest advancements in Apple platforms and test apps for compatibility
As for getting your Numbers in a working condition:
The FAQ at beta.apple.com states:
Install the beta software only on non-production devices that are not business critical. We strongly recommend installing on a secondary system or device.
If you need further assistance, please note that you must restore to previously-released software prior to contacting AppleCare.
Since you already turned the device off and back on, the next step would be to Reset All Settings (see below)
Would downgrading be advisable?
Follow the instructions in How to uninstall iOS or iPadOS beta software
Once beta is removed, then you can be provided support from Apple Support directly.
Note: This is not "downgrading", but turning off beta updates and then restoring your device to the latest signed release.
Also last I checked, iCloud back-ups completed on a beta version will not be compatible with non-beta versions of that release. Ensure you're data is backed up through iCloud sync other means and install your apps manually after restoring.
Lastly,
If you don't want to remove the beta or restore the device, you can reset device settings in Settings > General > Transfer or Reset iPhone > Reset All Settings or restore the device without turning off beta updates. I'd definitely try the first one before restoring the device as it's less invasive, however this will reset any settings you've changed in the Settings app (Notifications, Accessibility etc..)
Good luck and let me know if this helps.
Travis
