Potential not yet attained
Ok if you are a uk citizen and have a residence in the uk it is potentially great. But very limited if you live and reside abroad, you can not fill in online tax returns via the app or the gov.uk website. You can not upload documents to the tax office either. And worse still the amount of cookies and data analysis is absolutely over the top. Over 50 it would appear even if you said no to tracking. Seems every document they send abroad has the message saying it is possible to file online then you try and get a notice at the end of filling not possible to submit. Seems you need to learn how to do it from Scandinavian systems. So much more efficient private and secure.
