I've followed the guide and have everything that need working. Thank you.
Google maps, drive and photos work. YouTube too. All notifications seem good and I use the Aurora store and have framework app disabled.
I can't get Google Fit working and Garmin App never displays my routes. Neither are show stoppers but would be nice to find a solution.
Curve works well instead of Google Wallet/Pay.
I've been able to disable or uninstall various Huawei apps including the browser, so it's de-chinesed a bit.
So far so good.
What is your device and what version of Hrmony OS you are using?
