Contact syncing error in non apple watches

Hi

i am Raj continuing using iPhone for last 10 years . I have a suggestion for the improvement of the products. Recently I bought HUAWEI watch Gt 3 pro and I tried to sync contact from iPhone but it’s not working later only I realized that only 10 favorites contact can save in HUAWEI health app but iOS supporting for 3rd party app like wats up contact . So I can see the caller name those who are calling through watsup but no contacts from iPhone couldn’t able see caller name. I bought the product because of manly look of the watch but couldn’t able use the full feature of the watch . My humble suggestion is to give permission to sync contact in HUAWEI health then I can see caller name in watch in next iPhone update .

thank you
