Can't restore my purchase.

Hello, I have purchased LR yearly subscription on Google play. Right after I purchased it, it works prefectly. But several days later, my profile shows up subscription-out-of-date.

Then I just cannot restore my purchase. After I restore purchase in the profile, the welcome page of LR premium came up and told me "Purchase restored". But none of premium features is available. I have deleted and re-installed LR from Google Play but things still the same. Could someone plz help me with this? Thanks.
