Honestly, I understand that recording the concert can be annoying- especially in the standing audience but this is like normal for any Western concert. I understand that they want to protect their copyright and livestreams of the whole concert are lowkey illegal but banning mobile devices recordings entirely is so weird. A lot of people make films and recordings to have memories of the concert. Heck, even I filmed a few performances. Banning it, makes no sense imo. I am not talking about those people who only have their phone in hands and record the whole time. I am talking about those people - if not most people - who record their fav song and that’s it.
Also if you do not want to have so many people illegally livestream, how about make an official livestream???
