On my fully updated iPad everything is still present in the correct places. Have you done a delete and reinstall of the app?
Hi thanks for this - does seem a little odd that major functionality seems to disappear randomly - not sure what form of software development practise would have this as its operational model; additionally, the idea to me of a watchlist is a qui,c ‘go to’ for something you watch frequently - so why make it impossible (nearly) to find? At least with the Amazon and Netflix apps they leave the core elements in place around any upgrade and no major functionality suddenly just disappears!
