Hello @korchev,
After a couple of days trying solutions, creating a new .net8 web assembly standalone app didn't fix this. However, I have noticed that a service call to microsoft graph was delaying this action.
It is complex to explain by text but, this code:
builder.Services.AddGraphClient(baseUrl, scopes);
makes the filter/sort work slowly. In fact, when entering the page I showed you in the video, deleting the cache makes the filter and sort work instantly.
I don't know if this is because the service makes a call to a server and never finishes until the sort/filter is executed the first time and breaks that action or what can be the problem. I'm looking into ways to fix this. If you know any similar case I'll be glad to read about it.
