Syncing PC Chrome to iPhone Safari

Hello all,

I've read numerous Apple support articles and 3rd-party Web pages purporting to explain how to synchronize an iPhone's Safari bookmarks with the bookmarks in your PC-based Chrome browser. Essentially they all give the same instructions:

1. 1. Enable Bookmarks in the PC's iCloud app
   2. Click the Bookmarks feature's Options... button
   3. Enable the PC Web browser(s) whose bookmarks should sync with the iPhone's Safari Web browser
   4. Click Apply and Close

Unfortunately those instructions fail on my PC. I've had IE selected for syncing for several years, but my IE bookmarks have never appeared in the iPhone's Safari browser. Also, the iPhone's Safari browser has never saved a bookmark of its own via the mobile UI, even though I've attempted to do so dozens of time using varying methods.

On my PC, I recently switched to Chrome as my main Web browser, and taken the time to consolidate & rationalize bookmarks from the PC-based IE, Edge, and Firefox browsers into a single set of bookmarks in the PC's Chrome browser. Today I decided to see if I could succeed in syncing this unified set of bookmarks within the PC-based Chrome browser with the iPhone's Safari browser. It was even less successful than attempting the PC IE <-> iPhone Safari sync...which I think is really saying something considering an IE <-> Safari sync has never worked.

My steps and results

1. 1. Ensure the PC's instances of Chrome and the iCloud app are the latest gold releases.
   2. Google how to set up the sync process. Choose current instructions found on an Apple help site.
   3. Open the PC-based iCloud app.
   4. De-select, then re-select, the Bookmarks feature. Click the Bookmarks Options button, de-select Internet Explorer, then select Chrome. Click the Bookmarks Options dialog's [OK] button, then the iCloud app's [Apply] button.
   5. The PC-based iCloud app displays the following dialog:

iCloud Bookmarks extension for Chrome required

iCloud Bookmarks extension for Chrome is required.

Enable the extension to keep your Chrome bookmarks up to date with the Safari bookmarks on your iPhone, iPad, and Mac.

[Enable...] [Cancel]

The odd thing here is that this extension is already installed and enabled in Chrome. When I click on the dialog's Enable button, iCloud just opens a new instance of Chrome, with a blank tab & page displayed. This bug prohibits me from moving forward.

Anyone been through this and know the solution? I'd be in your debt.
