Luckily at my school RCT isn't removed (yet). I always use RCT on my phone anyways, on 4G.
But here I have another problem, dutch schools are recently in a race to forbid mobile phones COMPLETELY. Whole school day, no phones during lessons and breaks. The school I go to only forbids phones during the lessons, but they're thinking about completely forbidding it.
The teachers reported me one year ago for using my phone during a lesson and next day I had to pick it up 1 hour after my last lesson. Now they got seriously way stricter, they can kick you out of the school for a week if you show phone too often.
