I find the convergence typically by design on the part of the Designers, PMs, and decision-makers up top as opposed to their actually being a need for convergence. I often attribute this to a strong lack of diversity of teams whereby there are almost zero Android users on the design/product team leading to a unified look.

It can also be attributed to laziness on the part of the PM and/or designer. Or in general, clients opting for cheaper solutions when hiring an agency to build apps for them.

I say all this to point out that, Android users often get the short end of the stick when it comes to app design. Often there is a strong lack of consideration on what is a native Android app feel. No consideration for the use of back-buttons, menus and UI elements using bottom navigations or custom ones instead of native Material design... Generally convergence is made for all kinds of reasons that ultimately leave Android users alienated.
