Go Professional 6250 app won't send to device
I've recently purchased the TomTom Go Professional 6250.
After initial setup I could send the planned route to the satnav from my phone's app however after only using it once this feature has stopped working.
I've updated the satnav in case it's software related but still the issue persists.
My phone is android (Huawei P20 Pro).
I've also checked to make sure the satnav is synced with my my drive account and both devices are connected and synced.
Hope you can help.
