Hi bro, I transferred your question to the relevant thread

Anyways, here are the answers: -
1. Waze - Installed via
Petal Search.
Works without problems.
2. WeChat - Sorry, I don't use WeChat, but it is available in Huawei's AppGallery, hence I'm assuming it works without issues
3. Starbucks - Installed via Petal Search, works as normal
4. Maxis - Installed via Huawei's AppGallery, works as normal
5. Grab - Installed via Petal Search, works but can't pinpoint a location on the map. I've used GrabPay and Grab Food (delivery to saved address) without any issues though.
6. Touch N Go (am assuming you mean the e-wallet app?) - Works as normal, installed via Huawei's AppGallery
7. Facebook - installed via AppGallery, also works as normal
8. YouTube - using Youtube Vanced as an alternative - no ads and has PIP mode without needing a paid subscription. Bliss!
For me so far, the two main apps I missed are CIMB Clicks and Air Selangor (to pay my water bills, hahahaha) - no options for those just yet.
Hope this helps.
Thanks mate. Yes, you are of tremendous help.
Besides looking at the other phones which for various reasons I am procrastinating buying, I now will definitely consider Huawei P40 Pro, a phone if not for the lack of GMS, I would have bought much earlier.
Cheers.
