There are many that had issues with those visas due to changes.
We helped as many as we could, and we also contacted all of our clients to message us if leaving so that we could ensure hassle free entry if possible.
This specific situation was related to a 1 week event, which was 100% out of our control.
For multiple reasons we have no intention to change any of the existing rules. It will remain to be strict against discussing using agents, as the focus is on how to resolve your visa situation on your own.
If you wish to use an agent, a group is not required.
I know it sounds weird, but for us this does actually make sense.
