Can I enable thinking some other way?

via

OpenAI

After upgrading to gpt plus from standard, the thinking mode disappeared and got replaced with deep research quizzes etc. Now whenever I need it to think I have to type "Think and give me a detailed answer with your reasoning" etc. on every single prompt I send. This gets tiring. This feels like a downgrade which I paid for. The button has disappeared and hasn't been there since for close to a month. I use the android app if that changes things. Any ideas?

This is so cool. You can talk to an AI only trained on pre-1930 text. Really feels like talking to someone from the past.
