I have the same problem the Alexa app forces me to change my Language to English (Australia) and now the ewelink skill is not available anymore.
Please fix this as it was really useful and I will have to move to google home otherwise.
I have reported the same issue. They have confirmed that this skill is not available for AU region as of now and they would be rolling it out 'in near future'' , but they did not say when ... :(
They say ' it was submitted and under checking'.
