Discourse not rendering full page on older iPad

Bug
1

I’ve had a report from two separate users of my forum that the site is unusable as nothing is rendered beyond the topic title on their iPads (one is an iPad mini 2; unsure of the vintage of the other).

I asked one of the users to check in safe mode and the problem remained.

Apparently this issue came about in the last few days (I recently updated Discourse). Possible browser incompatibility introduced?

Do they work in safe mode?

The iPad Mini 2 is from 2013, so it is quite old. Its end of life was 2017.

I believe this is because the entries polyfil was moved to the IE plugin cc @joffreyjaffeux

Yes Object.entries is 10.3

AFAIK we support safari 10+ and ios 10+

So there is a plugin I can install to make this problem go away?

No this plugin is installed by default with discourse now. What am saying is that this polyfill was added to support IE11 months ago.

When we created this plugin weeks ago we moved everything added to core for IE11 inside this plugin.

Only requests made from IE11 will add files from this plugin, this is why ios 9 is not working anymore.

Ios9 usage is almost not tracked anymore, it’s probably way below 1% ( IE11 is at 1%).

This being said we can do two easy things:

  • add back the file in core for one more year
  • also load ie11 polyfill for ios10 and less, it’s a good solution given we can now conditionally load this without impacting everyone else.

Your call @codinghorror, my feeling is that we should stop supporting this, but Im fine keeping it if you think it’s more reasonable for now.

This is the way it is; extremely old and obsolete iOS devices can’t be supported forever.
