When exporting a character sheet to pdf on mobile then viewing this on the mobile device the skill abilities and inventory are upside down.

I tried this with my computer and on computer it works correctly.

All of my character sheets do this now. I just made a character using just basic stuff no supplements and it still does it with the brand new character: www.dndbeyond.com/sheet-pdfs/lisliaer_46468179.pdf 

Here's the original character: www.dndbeyond.com/sheet-pdfs/lisliaer_45664349.pdf

Tried using other pdf apps to varrying degrees of failure. Best I could get was just a blank character sheet no longer editable. Adobe is the only one that kept the editable fields.

Test character:  https://www.dndbeyond.com/profile/LisLiaer/characters/46468179

Those look like pc browsers, and to clarify they do open fine on pc. Just not on mobile. The characters also open fine in the player app and dndbeyond browser based character sheet, just isn't editable (to my knowledge). 

So I downloaded Firefox for android and tried and it cam up with the same results. I also went to the WotC web page and downloaded the character sheets there and none of those produce this issue. It is only the DnDbeyond pdf Char Sheets (AFAIK)

This remains an issue today. Many characters.
