All PDF notes on my IPAD disappeared!
A lot of work and effort as a student are just gone! I am shocked, one year ago I had another issue - all my pdf files disappeared.
I will never buy products from this company again!

Have you considered restoring your iCloud or iTunes backup to your iPad?

If your data is important to you, always keep a backup - this being good practice for any computer or computing platform.
Having insufficient storage for your needs always risks data loss. If you value your data, you must always keep a backup - regardless of your chosen device or computing platform - always being mindful of available online storage where used. The impact of exceeding your available cloud storage is not bug, but instead is an inevitable (albeit unpalatable) consequence.
All Apple Accounts have a free-of-charge 5GB iCloud storage quota, this being generally only being sufficient for synchronisation between Apple devices and storage of a few documents and photos. If you fill the available storage, there is always a risk that backup and synchronisation services will fail - potentially losing data as you describe.
Available iCloud storage can be easily increasing for a small monthly iCloud+ subscription - available storage tiers of 50GB, 200GB being accessible for a subscription equivalent to just one cup of coffee from a coffee shop; higher storage tiers of 2TB and more are also available.

To reiterate, you've not encountered a bug. As hard as it may be to accept, you have suffered an unfortunate consequence of exceeding your available storage.
You are not the first, and won't to be the last, to learn the hard way about the importance of ensuring that your essential data has been backed-up.
This aside, you should always choose computing devices that best meet your needs - be they Apple, Galaxy (Android), Windows PC or otherwise. Basic practices to backup essential data and documents are consistent, regardless of your choice of computing platforms.
My iCloud storage was full at that time, but the point is that it’s crazy to see such bugs. A lot of complaints relative to this theme in internet. I sell my iPad and MacBook and will buy galaxy tablet and windows laptop, It’s over for me.
you can let them know using their feedback channel
I never had such bugs with my Samsung. It’s not normal, especially for their premium prices.
these forums are user helping other users like yourself, it's sort of going
to a physical apple store and asking other customers their advice
All pdf notes are gone.
