just to cover the basics:
Those people and your squad are on the same platform?
There are servers for Windows players and different servers for iOS/Android Players.
If you're an android player you won't ever see windows squads and vice versa.
Same faction? (Rebels <-> Empire)
Other reasons for not finding a squad may be color identifiers in the name [00ff00]. But I don't see such in your squad name. So it couldn't be the problem.
(Rebels/Android/iOS). Just PM me here/LINE:lleyleber or request in game with a meaningful text. If you want to take part in wars, lv7+ is useful.
