Time between oversees entity registration and appearance in API

How long does it take for a newly registered overseas entity to be shown on the companies house website and to appear in the companies house api?
Today is the deadline to register overseas entities and their beneficial owners. How late this week can I expect to see new companies which did meet this deadline appearing in api responses from the /company and /advanced-search/companies endpoints?

There are entities with a registration date of today showing up in searches:

That’s just a random one. CH just sent out a newsletter stating that submissions are taking while to process due to high volumes, so there might be delays due to that, but it looks like when they are registered they appear pretty quick.
