Huawei P40 and P40 Pro certified with 22.5W and 40W chargers
Not bad 
That’s great charging.
Is there still issues with Google apps and Huawei phones?
What is happening is the combination of China and Europe, together twice the economic size of USA and 6 times the population, have had too much of the USA politics for over a year and are detaching themselves from Google, not so much against Google but against having USA dictate what they and cannot do. If USA had delivered a shred of evidence of their claims… but they didn’t.
So Huawei is using a combination of open source and their own app store.
In the case of the 40W chargers, that really must be a sign of Graphene batteries coming sooner than I had thought of 2021. Graphene recharges faster with less heat, so that causes a demand for faster chargers.
Graphene batteries are the really most important change in mobile technology for some years. Graphene is a 30% cost hike in 2020/1 so expect to see first in the very expensive items like flagship phones where the % cost impact is small, and in very small items like buds which don’t have big batteries anyway, then work into electric powered vehicles 2022/3.
