There don't seem to be any updates at all, which seems abnormal to me. They've been pretty decent with updates every time I can remember with outages but it's just silence and the outage site doesn't have info-it clearly works but there's no data populated. Purely speculation but it leads me to believe there is a relatively large problem that they dont want to discuss or the government doesn't want them to discuss for some reason (more Texas grid embarrassment?). I think most of us would simply plan accordingly if they came out and said "it's going to be a week or two". But that's probably giving too much credit to the masses, who would cause mass chaos.
Speculation, but I think Centerpoint's in house (on premisis) network, which would likely be what they set up to detect outages based on meters they can read remotely, was affected by the outages. To your point, their website - and basics of their outage map - loads, which suggests that part of what you see online is hosted off premises (cloud), but needs on premises data to be useful (show current outages). Thus you can go to their outage map but get nothing in terms of data.
The emails / updates you get would be based on some algorithm analyzing Centerpoint's on premisis data and generating an automatic email. If their on premises network can't collect that data, then they can't generate and send that email / text update.
The lack of updates isn't a problem with "the grid". There is enough supply, unlike what happened to "the grid" during the freeze. Centerpoint, which is responsible for connecting power to the end customer, can't connect the supply due to trees, wind, etc. taking out the connection to the customers. This issue is compounded by not being able to have their on premisis data shared off premisis.
