Hello. About 10 days I can't send messages through templates, just free messages.
When I try to make the post, I receive that error: {"message":"(#135000) Generic user error","type":"OAuthException","code":135000}
I tried to create another message template, but the error persists.
In my template panel, all my messages are okay with no errorr. My number also is okay and I can send free messages.
Any one to help?
