Vitality tech is a disaster. They will put your premium up if you do not record sufficient activity... however, their tech is so terribly unreliable that you'll be regularly submitting screenshots to get Vitality to manually register activity, as it will routinely fail to sync/register activity. Trying to resolve it by seeking support on the website/app is a frustrating cycle of broken links, buttons that don't work, and repeatedly having to log in. The customer support channels are dreadful too. It all makes for an appalling customer experience, and I wish I'd never joined them
