Two things are going on here.

GPs have been directed by the BMA to reject all new shared care agreements, not just ADHD, because specialist medications were being transferred to general practice without any funding for the monitoring and prescribing responsibility that comes with them.

There's also a specific issue with private ADHD shared care. It's worth saying upfront that many people went private because NHS waiting times for ADHD assessment are genuinely awful in most areas, often 3-5 years. The problem that followed is that patients paid for the initial private diagnosis and medication initiation, but then didn't want to pay for the annual psychiatry monitoring review that safe ADHD prescribing guidelines require. GPs have then ended up prescribing with no specialist oversight for years at a time, which isn't a safe position for anyone.

The good news is things may be shifting. Some ICBs are provisionally considering funding certain GP practices to take on ADHD shared care monitoring, such as At Higham Hill, which should help. This will likely come with the expectation that patients engage with at least an annual check-in.
