The SageCell Doctor Page lists 11 different problems and solutions/workarounds for 3 of them. There have been no additions over the last months. I planned to keep the page open until the end of the year, but - unless more solutions are provided - I wouldn't object to taking the link off the SageCell start pagen ow .
But the issue I was pointed to is a different one:
I am using SageCells in an educational context, in particular to support explanations with realistic examples. Code in my cells is usually small but it is benefitial for students if they understand the particular code. In this situation it would be better (for students, I think,) to access through the help link infos on the SageMath language, rather than on the SageCell system.
It would be even better if I could provide a specific help link for each cell to explain the particular code.
