TS3 user can't see my ts5 current server chat message & I can't see my uploaded avatar

[城市不築敗事有瑜]

I can see my friends message in current server chat but they can’t see my sent message.
PS:They are TS3 user. And my version is the newest TS5 beta.19
But I still can use open chat button to text with one person.
And I still can’t see my uploaded avatar why?
I can see my friend avatar.
Please fix:)
