Cannot paste link in composer with Android Chrome: A discussion about a bug that prevents users from pasting links in the composer on Android Chrome.
The issue is specific to external links (Don) and seems to be related to a Chrome feature that prevents clipboard snooping (rrit). The Chromium team has identified the problem as a bug (andrei) and a fix has been merged (andrei), but it is not yet published.
The bug occurs when copying a link from the address bar using the copy button (andrei), but not when copying a link from a web page or copying from the address bar manually. A workaround is to make the link appear in the clipboard before pasting it in the composer (rrit).
Hello,
Repro:
It seems to only happening on mobile. I tried it on Android.
My forum is on e92f57255d but I tried it on Meta too and same issue.
I tested it with Android 10 Chrome 98.0.4758.87
Thanks 
Update: It seems to only the external links affected. If I copy a link in meta than I can paste it but if I go to a website and copy that link than I cannot paste it.
Just updated to 98.0.4758.87. Now I have the same problem. I can copy and paste the link posted by @Jagster . But not something I copied from the address bar. It seems to work if I don’t copy from the address bar
Wiktionary.org links like https://en.wiktionary.org/wiki/discourse don’t work…
discourse - Wiktionary, the free dictionary
… because of:
You can only see this note in preview on desktop - I think on mobile there is no preview?
Does it also fail on mobile for a link from Wikipedia.org like
https://en.wikipedia.org/wiki/Discourse_(software)
This looks like a new privacy feature of Chrome on Android to not insert copied links into clipboard.
Open website
Tap on address bar
Copy link via tap on icon
Go somewhere like Discourse composer and try to insert via “long-tap” → context-menu → "insert
This fails.
Have a look on your keyboard - there is the link and can be inserted:
Alternative:
Copy link and make it appear in clipboard.
Results:
And now you can insert the link anywhere - also via “long-tap” → context-menu → “insert”.
Yes, this is the same bug.
There is a bug report about it on the official bug-tracker - https://bugs.chromium.org/p/chromium/issues/detail?id=1295617. Note that you can vote for it. To do it, login via Google and toggle this button with the star:
This happens only when using the copy button on the address bar:
Everything works just fine when coping a link from the web page (even an external link) or when coping a link from the address bar “manually”:
I, personally, doubt that this is a security feature. That would be pretty confusing UX in my opinion. And I tried to find some announce of it, and found nothing. My guess is that this is a bug in Chrome, and the fact that the link appears in the clipboard after tapping the button with an eye is a side effect of pressing that button.
I’m pretty sure it’s all about preventing clipboard snooping.
Quite similar to the Android clipboard prompt feature: https://www.xda-developers.com/android-12-beta-features-leak/#android12leakclipboardprompt
iOS: TikTok and 32 other iOS apps still snoop your sensitive clipboard data - Ars Technica
Edit: @andrei so you were right, it’s not a security feature 
The team at chromium pinpointed the error to this feature: [Omnibox] Clipboard can set and detect URL mime type
The Chromium team merged the fix for this bug. Note that the fix isn’t published yet.
