FIX MY APP (CHROMECAST AND SOME LITTLE FIX)

Hi everyone, I have a streaming app but the previous developer ruined everything. There is a section where I put an iptv list but the chromecast doesn't work. If you agree to give me a hand know that: 1) I pay only at the end of work and only after you sent me the source code. I've taken more than a few scams here and I don't want to lose any more money 2) Accept the job only if you have chromecast and only if you can try all the work you do 3) I send you a pdf, read it and if you can do it all accept. Don't accept the job just for money because I want serious people and not people who make fun of me to make some money. If you think you can help me then contact me but if you only have one doubt, leave it because I have no time to lose :)
