え？？なんか傾向・人気のやつとかのプロジェクトだけ読み込まないんだけどこれってなんですか？？被害なかったらこっち側の問題かもしれません…

It might happen that the loading time of (some) projects is increasedly long or they don't load for some reason, which can be frustrating.
I experienced this issue myself already, being able to visit trending, profiles, studios but not the projects, albeit I am not currently experiencing it.
This is not a problem local to you, but I hope scratch has resolved this issue as there is not much that can be done about it asides from reporting it here and waiting.
