That's gold. Thank you! Yes the refocusing can be unreliable. Currently the more reliable way is press tab to refocus. I'll work on the landing page, as that hasn't been updated for months and it's slightly outdated and didn't even highlight the now available iOS app.
The refocusing issue is now fixed in next build. I previously spent many hours trying to fix it but O3 just one shotted it.... :D Thanks so much for the suggestion!
