Interesting. In German typography we used to use lower quotation marks at the beginning of a quote and lower quotation marks at the end of a quote, both in handwriting and print:
„Amazing“
But the lower version isn’t found on the default QWERTZ keyboard layout so in personal digital communication (instant messages, emails, etc) especially you find double upper ones a lot:
“Amazing” or ‘Amazing’
The formal spelling rules haven’t been updated and you may still find the lower-upper vision in professional publications where the software adjusts the quotation marks according to a global setting. But most anything that is typed directly by a user will use the lazy lower-lower version.
