Just rebuilt sll my links. Works fine: http://www.sosinvision.com.br/ips4/index.php?/links/
if you read all pages of this topic, you will see in all pages someone saying that nothing works, everything is bad, etc. then this person disappears in a few hours/day. The app works, otherwise ALL other purchasers would post here.
They’re free services and as such, they will stop working from time to time. There’s absolutely nothing I can do except ask you to wait for their service to become stable again. Just wait!
Ps: I’m not responsible for 3rd-party services. If they stopped working, it’s not my fault. My job is to provide a communication between your forum and a 3rd-party service, WHILE they’re working.
