Thanks @Nivedipa-MSFT. I don't know what help a screen recording would be - I have uploaded an image of my test tab not focusing(!) The code for this page is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>Focus Test</title>
</head>
<body>
<form>
<p>Testing focus...</p>
<input type="text" id="textBox" />
</form>
<script>
document.getElementById("textBox").focus();
</script>
</body>
</html>
If I view this content via a Teams personal app tab in Chrome it works as expected - the focus is automatically set to the text control when the app/tab is selected and I can type straight into it.
In the Teams Windows desktop app it does NOT work - the focus is not set and I have to manually click into the text box to enter text. This is an extra unwanted step for the user.
I hope you can help - I would be happy to provide any further information you need, or test anything reasonable that you could recommend. Thanks!
