People in Myanmar are Buddhists, they are not the dumba*ses you are used to seeing elsewhere.
This should get you started on Myanmar.

Here's a Western think tank giving India gyan, but it should help you understand the situation a little more.
Close ties with the junta risk leaving Delhi off side.

Simply put, the current regime in power is pro-India and anti-China, although they are smart enough to maintain balance between the two.
So India had pro-India govts in both BD and Myanmar all this while. America and China support the other sides in both countries, hence the American-led coup in BD recently. They wish to do the same in Myanmar, but the Junta is a bit too powerful for that. Russia toes India's line on Myanmar.
That's the problem between India and the West. While both are aligned when it comes to China, the West is constantly working against Indian interests in the Indian Subcontinent, be it Pak, BD or Myanmar, even Sri Lanka and Maldives. And we use Russia to balance out the equation 'cause they have military tech and the UNSC veto. Another example of why Western civilians are too naive to understand why India won't be abandoning Russia anytime soon.
