I am using the Moodle mobile 3.3.1 and Moodle 3.2 website. I found a bug on feedback comments when grading submissions through Moodle mobile for teachers.
I downloaded Moodle 3.3.1, the latest version from Apple Store, and linked it to Moodle official demo site (http://school.demo.moodle.net/). I logged in as a sample teacher and access “assignment 2 (upload)” to module “Digital Literacy”. The grades and feedback comments of submissions can be uploaded successfully. However, when trying to add some lines in the feedback comments I already wrote, it cannot be sent to the Moodle site successfully. But if I deleted the feedback comments and added a new one freshly, it can be sent to Moodle site. It has the same problem in Android version. As there will be teachers update the comments based on their previous input, it will become a big problem. I hope someone can fix it as soon as possible!
In addition, after the feedback comment has been sent to Moodle site successfully, I clicked into the comment box and view/edit the comment. The comment is in html format. It will confuse teachers, as most teachers do not understand html tags. It does not have this problem in Android version.
