Trello stuck at loading after Safari 14.1 update on macOS Mojave 10.14.6

Anyone else experiencing the same thing? I don't have access to my Trello boards on two machines (both running the same macOS, both just after Safari update). Just "Trello" at the top, empty button in the top bar, loading animation in the center.

Still can access with Trello app.

The issue is fixed for me a few hours ago. I hope everyone else is able to use Trello Again on Safari and Mojave.

Yes, working now.  Nice to have the desktop app as a backup.  Still wondering what will happen if/when I upgrade to Big Sur.

Thanks for confirming Cassandra. This change rolled out around 2.5 hours ago, so I'm glad to hear it solved it for you.

Hi there,

We've been able to reproduce this bug on our end so our team is investigating what is causing this. I don't have an ETA on when a fix will be available but hopefully we're able to roll this out soon.

As Michael said above, the best workaround for now is to use a different browser.

Thanks for raising this!


Good to hear that you are on it. Hoping for quick fix. 🤞

I'm having the same problem.  Uploaded a security update to Mojave this morning. Does anyone know what happens if we update to Big Sur?

Yesterday we were able to find the cause of the issue and implement a fix. The problem was isolated to the recent Safari update (14.1) on macOS Mojave. The fix should be rolled out within 48 hours.

For anyone that may be interested: it was caused by using the 'compact' notation for the Intl.NumberFormat API. We use this to localize shortening of long numbers. e.g. presenting "1,825,602" as "1.8M". For now we've switched to 'standard' number formatting for Safari 14.1 on macOS as a workaround while we continue to investigate the changes in Safari that cause compact formatting to fail.

Awesome, thanks for your help!

Definitely having the same issue here. Was wondering what was going on. The Mac App from the App Store and Chrome both work fine, but in Safari, after updating, it's stuck on load. Seems to work fine in Safari on mobile and all mobile iOS apps as well. It's just the Mac Desktop Safari browser 4.1. I'm on Mojave 10.14.6.CleanShot 2021-04-27 at 15.19.12@2x.png

Yes I'm having the same issue. after the most recent Safari and Mojave updated.

We are looking into it. AT the moment the only workaround I know would be to use a different browser but I’ll update if I learn more.
