It took me about two weeks to get Google to apply the Gift card to my account. They basically lied and then refused to discuss why there were the issues. I stuck at it several times a day and eventually was able to use the gift card for nebo. I'd especially got the tablet and the gift card to run nebo.

I'm hoping with the new EU DMA since March that eventually more companies will sell Android apps direct, or have free demo on Playstore but in app upgrade is a direct purchase.
Xodo annotates PDFs but the 2 page view starts on the Left, which is wrong! Pocketbook has 2 page view for epub or pdf and the first pdf page is correctly on the right (For Left to Right languages and books, I've not checked Hebrew, Arabic, some Asians etc). It means when proofing a PDF for print that Pocketbook has the margins (inner and outer as per paper bound) but Xodo has them reversed. Usually the inner "binding" margin is larger than paper edge margins for novels.
Xodo does no conversion of annotations to text. Nebo allows any mix of drawing, handwriting, and converted to text handwriting on an imported PDF, which can be exported.
So I use Xodo for old magazines and PDF generally, Pocketbook for epub and proofing PDFs, and Nebo for advanced PDF annotation, shapes/charts like OneNote/Visio, writing as text, drawings and organisation in heirarchy.
Jota is good for plain text either USB, BT, touch keyboard or Google Gboard handwriting to text (finger or pen).
