Hey
I’m not sure if you guys are aware about this but there has been a complete revamp going on when it comes to google assistant, where google gemini is taking over and replacing assistant by default, which is pushed through the software updates to the Google app.
I installed gemini app on my old phone and opted for gemini replacing google assistant and I noticed that it is just not like assistant anymore, it was more like a chatbot and not exactly assistant, as google is yet to fully integrate it into Android.
Try this - Change the default assistant back to Google Assistant in the Google App settings under Digital Assistants from Google.
