Search bar, App, Watchlist not working

The search bar wasn’t working for me. I changed from wifi to mobile network still the issue didn’t go. I logged out thinking it will be resolved but it created even more problem. When I logged in again all my data was lost there was no watchlist or history. All of it was gone. Things like search bar not working had happened before but whole data being lost never. I had complained about it through email, tweeted, asked in app help section also but didn’t get any response. I need that data. Please help me with this!!

Are you using Moviebase in India?
