Summary:
- open important page* on iPhone, using Chrome (* cat photo)
- on Chrome on macOS or Chromebook: three-dots > History > iPhone
There are stanzas for each device I use. The links get synced pretty fast but not instantly, sometimes you have to wait 20-30 seconds.
The above is also an easy way to share a page on the Chromebook, with someone in an SMS message or WhatsApp using iOS. Just reverse the above process.
