Spreadsheets blank after update

[MaxTKB]

Hello,

Can anyone shed some light on why my custom spreadsheets (under apps) are now blank after applying the latest firmware update. I've tried restoring backups and still the spreadsheets show up completely blank. I can see in my backups that there is definitely content in the files, but maybe the new firmware update can't recognize the content (formatting may have changed?).

Any advice would be greatly appreciated, I use about 6 different sheets on a daily basis to help with my layouts and developments.

Thanks,
Brian
