@Nihonmir Thank you for your comment. We apologize for the inconvenience! We have had similar reports of this happening when users had included an extensive amount of information in their notes. We are having trouble replicating exactly what the tipping point may be, since no amount of plain text seems to cause this bug. If you wouldn’t mind sharing what your note consists of (headers, stylizing, bullet points, links, etc.) for this particular grammar point so that we can get to the root of the problem and get it fixed, we would greatly appreciate it. Thank you for your patience! Cheers!
Edit: We have figured out the issue with the notes and will be pushing a fix with the next update. Thank you for your patience. Cheers!
