After try for my colleague download successfully and I tried again another friend also ok.
The step as follow:
1) Go to Chat click on right top corner +
2) Click on Money
3) Enable Pay Vendor
4) Add visa card and name, address .....etc
5) The wallet will appear
If still cannot, I can send you a red packet and you go and open it and add the Visa card and the wallet will appear.
Hope the above can help.
How do I send red packets to other wechat users? I've set up my wallet and topped up some money (from a friend) but I don't see the option to send red packets (it should be available in the + button of the chat window but I don't see it there).
