Why has there been a lack of news about what the members of GFriend are doing?

They are probably enjoying their rest and privacy during this break (with offers and negotiations ongoing back door), just like other IZ*ONE members.

It's still a shame they disbanded.

I think what Umji mentions in the main article describes it well:

After their leaving the company, there's a gap where there's so many things they have to figure out by themselves now, with such a radical change of lifestyle and day-to-day life, a lot of things that the company and their managers used to provide and support them with when they were still with the company.

maybe just chilling to decide what they want to do next with their lives...
