Chromium Google search autocomplete not working on Mint 20

I installed Chromium on Mint 20 using apt following the docs [here](https://linuxmint-user-guide.readthedocs.io/en/latest/chromium.html)

$ apt list chromium
Listing... Done
chromium/ulyana,now 87.0.4280.66~linuxmint1+ulyana amd64 [installed]

Then I added Google as the default search engine for Chromium. But when I type into Chromium's address bar, no suggestions from Google show up. Google autocomplete is working just fine after adding to Firefox following [these docs](https://www.linuxmint.com/searchengines.php) . Also the autocomplete works for other search engines (e.g., DuckDuckGo) included by default with the Chromium install. Did I install or configure Chromium wrong, or is there something in Mint 20 blocking me from using Google search with Chromium? (I've never had this problem on Ubuntu, macOS, etc.). ### Edit Here are my Chromium settings for "Sync and Google services". I have autocomplete enabled. Tried with all enabled, still didn't work. Search engines that came default like DuckDuckGo initially had autocomplete working in Chromium, but when I removed them and re-added them autocomplete stopped working for them also.
