Mobile access issues on iOS

So, as we are growing our database setup and adding users, we are running into some issues with some, but not all iPhone users. I have 2 users with iPhones with no issues, and my Android has no issues. Some iPhones it acts like the page tries to load after login, then crashes. and gives an error. If you log out, clear the browser history, and restart the phone, sometimes it will go ahead and login and give proper access and use, but not always? We checked that JavaScript is on, and of course it is, because it does work sometimes. It seems like something isn’t releasing, or is causing a block of some sort? The document that is being opened only has a few simple pages as well. Has anyone else ran into this problem, and if so, how did you fix it?

Is this on a particular iPhone browser?

I vaguely recall an issue like an infinite loop on load, on iPhone Firefox, but that was a while ago and I thought that got fixed. The symptoms were a page that was not only unresponsive but made the browser controls unresponsive for a while too. What error are you seeing?

It is happening in Safari. We also tried to install Chrome, but the same thing happened in chrome. The browser doesn’t lock up, and you can still get to settings etc. It just throws an error almost like it is using too much memory or something, and can’t fully load. So far the only temporary fix is to log out, clear Safari history, reboot, then you can log in once. If you leave and come back where the page refreshes, it happens again.

I have at least 3 users with iPhones, that don’t have this issue, so I’m assuming they either have a newer iPhone, or a pro or something more powerful?

I’ll try to see what the error is exactly, when I am together with the user tomorrow. Mine is working fine on Android, so unfortunately, the only way I can test it is on another users phone

The error says "A problem repeatedly occurred on “https://…”

The https is my document and company.

This is on a iPhone 15 with IOS Version 18.5

Using Safari that is up to date

Hi Nate, did you ever figure it out? Grist does get more testing on Chrome and Firefox, but Safari ought to work: Browser support - Grist Help Center.

I tried on a few small and large-ish documents, and wasn’t able to reproduce on iPhone / Safari (this was on iOS 16.7).

There seems to be a wide variety of potential causes: javascript - Debugging a iOS Safari crash "A problem repeatedly occurred" - Stack Overflow. Some potential causes could be due to what’s in the document (e.g. image attachments, markdown cells, custom widgets?) If this issue is continuing, and if it’s on a document you could share with Grist Support, we could try to reproduce and pinpoint it.

Thank you for reaching out again. No, I have not figured out how to get it working yet. I just sent a detailed email, containing the document and more details, so you can check it out. I’m going to keep working on it on my own as well in the meantime. I’m going to look into the custom widgets and see if they are possibly causing an issue? Thanks
