Similar. Gem store splash page is visible, but nothing can be clicked on. Currency exchange is completely non-functional (trade values don't populate, no buttons interactable), TP appears to let me search, but not buy - and "recently viewed" history on the front page is not working either.
Actually the first thing I did when I logged in today was to redeem some gem card codes (because Kitty!) before I was aware of problems, and the redeem code button did indeed work just fine, entered codes got "Redeemed 2,000 gems" message for each code instantly - but it took several minutes for each of them to actually credit to the gem value, so much so that I worried they have just got lost in the aether.
Now I have gems but still can't buy a Cat costume, or even convert the surplus to gold. Sadness.
