When I open up the Minecraft launcher on my computer, the button that says "play" says "play demo" instead, and it has a box on the right that says to buy the full version. I already bought Minecraft so this is weird, but I went to try and buy it again, and that takes me to the "If you already bought it, download it again" tab, so I download a new launcher, but when I open it, it shows the exact same thing. There's also a tab on the bottom of the launcher screen that says it couldn't connect to Minecraft services, and there's a refresh button, but that does nothing. I recently created a new email and I replaced the old email linked to my Microsoft account with my new one, I feel like this might have something to do with my issues, but I can't say for sure. Either way, I only have access to the Minecraft demo and I can't tell if this is a bug or not but I hope this issue can get resolved.
