I tried downloading it but it says that "The type of file may harm your phone". Is it really safe to download that app in an android phone? I tried joining you on Telegram as well but I couldn't find it. Do you have a referral bonus limit?
I think you have just a security notification through your phone. Some android phone gives the user a notification that indicated the allowed resources or etc. Maybe, you just need to click yes because this app is not spy and it may not harm us since they need users. Thank you for being cautious.
