Hi Phil,
I am using the HERE algorithm an my default landing map in the browser is OSM. I don't have any issues.
No idea, why you are experiencing this issues.
I can change to and from any map and my loading speed is absolutely fine.
You might have heard that several times and think it isn't worth trying it, but anyway:
Sometimes it is related to your current browser and it can help to reset the browser caches and/or cookies.
This helped me from time to time using other web apps.
Greetings
Tom
