Adobe XD - Publish link not working (Error code 44:63)

Same. I can see in earlier posts Adobe suggest reducing assets or splitting artboards to resolve error 44:47 and 44:23, 44:63.  Not really ideal with live projects. I notice Adobe also shared the follwing troubleshooting solutions by code. Could be worth a try in the interim: https://helpx.adobe.com/uk/xd/kb/cannot-use-share-feature.html

Same here. Error 55:63
All my projects (public links) gone! Customers are very angry.

Same problem here and old links dont work anymore.
I thought Adobe XD is in maintenance mode: no new features but current features should still be usable?
Did Adobe just pull the rug on us?
