I’ve reviewed all 4 of your Answerhub accounts and I do not see a common that has affected other past users which we’ve been able to easily resolve.
I do not have a solution for the issues you are experiencing. issue would likely require involvement from the site vendor, but they have been unable to resolve related issues, and Epic is working towards a change to the website which will address these and other matters.
Apologies for the difficulties.
Update: I can now provide some additional context: Epic looking for your feedback on the direction to take with Answerhub
