[Bug]: App not loading on mobile / Safari iOS

[upbeat-eggplant]

Verified issue does not already exist?

• I have searched and found no existing issue
• I will be providing steps how to reproduce the bug (in most cases this will also mean uploading a demo budget file)

What happened?

The app does not load on Safari mobile iOS 15.8.3. Running actual v24.10.0. I have confirmed that the same error occurs on the demo site and is most likely not caused by my setup.

Error on 24.10.

---

I have also tested actual 24.8 (https://deploy-preview-3179.demo.actualbudget.org/) which is working, while 24.9 (https://deploy-preview-3348.demo.actualbudget.org/) shows a different error than 24.10 but is also broken.

Error on 24.9.

Thank you!

👋 The most likely issue here is missing Regular expression support for lookbehinds (support for it was added in safari 16). We use that for the tagging functionality.

The easiest way to fix this is: upgrade safari and/or ios on your device.

Hey, thank you for the reply. Unfortunately, I am running the latest version supported on my iPhone 7 and iOS 16 is not available.

That's fair. I'll keep the issue open if someone wants to take a whack at this.

Thank you! I would understand if the project decides not to support this somewhat dated OS anymore. Altough I feel that this decision should be made transparent in some way.
Do you think it is safe to downgrade my installation from 24.10 to 24.8 in the meantime?

Ideally we would support older iOS versions, but personally I don't have a way to test this and thus fix it. So I'm hoping someone else in the community steps up here and works on a patch.

As for downgrading: feel free to do so (although it might be quite tricky.. we don't really have a 1st party support for downgrades). Feel free to reach out to the community on discord if you need help downgrading.
