Test code: 

   navigator.clipboard.writeText('test 1').then(function() {
       console.log('Copy to clipboard successed 1');
   }, function() {
       console.log('Copy to clipboard failed 1');
   });
   
   let test = await crypto.subtle.digest('SHA-256', dat);
   
   navigator.clipboard.writeText('test 2').then(function() {
       console.log('Copy to clipboard successed 2');
   }, function() {
       console.log('Copy to clipboard failed 2');
   });

Logs:

Copy to clipboard successed 1 Copy to clipboard failed 2

Test code: navigator.clipboard.writeText('test 1').then(function() { console.log('Copy to clipboard successed 1'); }, function() { console.log('Copy to clipboard failed 1'); }); let test = await crypto.subtle.digest('SHA-256', dat); navigator.clipboard.writeText('test 2').then(function() { console.log('Copy to clipboard successed 2'); }, function() { console.log('Copy to clipboard failed 2'); }); Logs: Copy to clipboard successed 1 Copy to clipboard failed 2

See: https://developer.mozilla.org/docs/Web/API/Clipboard/writeText

I think the problem is that the second write is not directly linked to the user action that triggered the function.

The two test writes are in same function, only split by one line code of the "crypto.subtle.digest()".

I hope you can try my code, it's easy to reproduce the issue.

I think calling the asychronous function disconnects the second call from the original user-initiated event.

This old (open) bug may be relevant: https://bugzilla.mozilla.org/show_bug.cgi?id=1185052

Thank you for your reply, but I think they are different issues, I tried call some other async function instead, no problem at all.
