If typing your show name in the search bar doesn't return anything, you should first:
- Check the internet connection is working fine on your phone.
- Check you can find an alternative popular show (i.e. Desperate Housewives) to see if it's not a server-side probleme at tvmaze.com. If it's the case, just come back in a few minutes, it may be short outage sometimes.
Either the show is not available at tvmaze.com or it is available and an issue is making it incompatible with current version of TST.
If the show is available at tvmaze.com and doesn't show up in search, this is a know issue and it will be fixed in upcoming update (3.6.3).
