Such a shame..
I love telegraph puzzles - have a subscription and play on the website all the time, but this app needs some serious work - puzzles don’t load and when the app is working the ux makes you want to cry (can’t delete letters, goes over completed clues, generally extremely frustrating to use). Telegraph are missing out on revenue by not having an app that can compete with NYT and attract non-US English speakers who get annoyed with the Americanness of NYT puzzles, but it seems not a priority.
