Cannot Paste into Notion - (NOT an Ctrl+Shift+V Problem)

I am using Notion through Mozilla Firefox on Linux Mint. I cannot get lists to paste into my database. Here is what I have tried:

1. Ctrl+V and Ctrl+Shift+V

2. Ensuring that the cell is blue (selected/highlighted) and also ensuring the whole line is blue/selected.

3. I have tried in windows, and in linux, on edge and firefox.

4. I have tried in different databases and different Workbooks or whatever they are called in Notion. It doesn't work no matter what database I am using.

5. I have tried restarting my computer

6. I have tried disabling blockers/VPN and using my phone to hotspot

7. I have tried copying a list from an existing Notion database into another one

8. I have tried copying from Word, Excel, Libre Office apps, etc.

9. I have tried the Desktop app in windows.

I can get the text to paste into a cell (so, the entire list is in one cell). Therefore, I know that Ctrl+C and Ctrl+V are actually working.

Pleas help! I have so so so many lists to move into Notion and I cannot type them all by hand. Importing sucks and never works right.
