@sudheerDev You have previously fixed issues related to keyboards - is this one something that you’d be able to investigate a fix for if I open a Jira ticket?
@sudheerDev So I tested in Chrome and Firefox
Chrome 71.0.3578.98 : works as expected
Firefox 61 : same issue as Desktop client
Firefox 64.0.2 : works as expected
For Firefox I cannot garantee that the issue was due to the version, maybe a restart would have been enough.
As for the expected behaviour : with the Belgian layout, the tilde is handled like ¨ ^ and other caracters that are supposed to go on top of other caracters, so, at first press, nothing appears, at second press, two appear (or you can hit space after the first press)
