At about step 5 the flow should pick the middle of 3 tabs at a given web page.
Since updating Edge this morning I can see that it's selecting that tab - but it doesn't actually go to the page under the tab so that when a subsequent step tries to select a field under the middle tab, it don't find the field and fails.
Tried, so far unsuccessfully, various workarounds. E.g. respecifying the UI element to select - however that's not really the problem. The problem, as best I can see, is that events aren't firing after you select the tab to transfer focus there.
