GUYS LETS REQUEST BMS AND WHOEVER IS RESPONSIBLE SO THAT THEY ALLOW POWERBANKS JUST LIKE THEY DID IN ABU DHABI

So I have heard that powerbanks are not allowed in the concerts (mum and ahmd) but practically speaking till the concert starts half of the phones are going to die (esp the ones with an IPHONE) so I thought if anyone here knows a way where we can all request them to allow us??? maybe? just a try???

IF ANY ONE HAS ANY IDEA HOW TO DO THAT PLEASEE HELP…
