I had been doing a lot of business from the country but their narrative about India had taken a complete Uturn I feel. No, business now at all at my level for more than 6 months now. I believe that the islamic narrative had spread its wings much before Hasina's demise.
For the controversy regarding US's involvement, I can't say much. But Bangladesh, even if it becomes a complete Muslim country, would not want to make bad relationship with India.
Like you see they have acknowledged, the water has come down through India, if all dams are opened, Bangladesh would be nothing in 24 hours!
