I use Firefox for Android 68 on Android 9.
Since [2021-06-05](https://chatlogs.metabrainz.org/libera/musicbrainz/msg/4816383/), [community.metabrainz.org](http://community.metabrainz.org) is just a blank page for me, whether logged in or out.
I tried the included Chrome browser, same issue.
Meta however works OK.
MetaBrainz Discourse is `Discourse 2.7.2 - https://github.com/discourse/discourse version 81070b323f4679e3052efe64b5db7fecada10f23` which is older than meta `Discourse 2.8.0.beta2 - https://github.com/discourse/discourse version 940eb28e31636cf585a27daa92a1e86a14238423`.
I tried on an older Android from my office and there it works with Samsung browser. π€
Any clue?
Here are errors that only occur on [community.metabrainz.org](http://community.metabrainz.org) (blank page):
```plaintext

```
Update: I removed the `Content Security Policy` errors that were common to [meta.discourse.org](http://meta.discourse.org) and [community.metabrainz.org](http://community.metabrainz.org), it was just distracting and irrelevent.

Firefox for Android is currently on version 88.1.4, can you reproduce on that? It loads just fine for me on the current version:
Still, neither version is officially supported, as we only support Chrome on Android.

FYI - We have heard similar complaints after updating forums to 2.7.2: mobile site going completely blank. We do not have any specifics about the client OS or browser though.

I know but only 68 does support add-ons (I need [Violentmonkey](https://violentmonkey.github.io) on mobile, to check my CD collection when in second hand shops).
And it is also blank with the built in browser (Chrome).

I canβt reproduce that on neither Firefox nor Chrome on my Android phone.
Also opens fine on my desktop.

Ah. Maybe itβs because Iβm logged in.
I will try to identify all the possible cases where it works and does not work.

Thanks very much for your feedbacks.
Indeed it works with more recent Chrome!
For the record (in **bold** , my own setup; others are from my job test phones; ~~striked-through~~ browsers have no add-ons support):
| Browser | Mobile OS | [community.metabrainz.org](http://community.metabrainz.org) status (2.7.3) | [meta.discourse.org](http://meta.discourse.org) status (2.8.0) |

## Work-around
As a work-around, I have updated Chrome and installed the Discourse site as a _desktop icon / favourite / app?_ and will use that until [community.metabrainz.org](http://community.metabrainz.org) (now in version 2.7.3) reaches similar recent version like [meta.discourse.org](http://meta.discourse.org) (version 2.8.0) that is again compatible with Firefox for Android 68.11.0. π
Long touch on links allow me to open links in Firefox. Slightly slower but good enough for me.

I prefer to just transpile up to say 2-3 year old Firefox / Chrome, but am happy to leave that call to @eviltrout and you, we can go more aggressive I guess, but we can not display broken pages Edit, see backlink, this can be a pretty serious issue on android that tends to have terrible cadence upgrading browsers

Hi @sam,
**Discourse version 2.8.0, used here on meta has no issues, so no need to change Discourse code** for this issue, I think.
We just wait for version 2.8.0 and it will be fixed.
Meanwhile we use another browser.

Yes but the mentioned _fix_ would apparently be to serve a static read-only HTML version to those browsers.
So I prefer waiting with no changes, as this more recent version of Discourse, here on meta (2.8.x), does work with those browsers in full featured mode (maybe thanks to transpiration).

No, I think you misunderstood.

That was probably not on purpose, but it made me smile π

Super, then! ππ
I saw the unintentional typo, but then I intentionally left it like that. ππ€
It will be fixed! Super!
