I am also experiencing problems with the TP but mine is a little bit more weird.
everytime i open by clicking ’’O’’ or local TP the window opens correctly but when loading the Gem store it stays blank, like many of the other posts in this thread, BUT… when trying to BUY or SELL stuff, it shows like a broken HTML page, with its white tabs, the blue-clickable button for other things and the gray unclickable button for search…
I CAN’T buy stuff, i CAN’T sell stuff
