That is some challenge. For one, we need to include as many as mobile users as possible. If the challenge comes from the core OS itself, we need to lean on to the most used OS. For example, a mobile banking app. If Android has no/ less restriction for "tap to pay" feature than that of iOS, then it makes sense to prioritise the app on Android. Later on, if the core iOS allows such feature in its future update, we can develop the feature on iOS by then.

What really comes down to is if there is a need for cross-platform communication. Most companies do (the vast majority), but understanding your need is what's most important for what you're trying to accomplish.

Priorize testes em ambos os sistemas desde o início, use frameworks que suportem multiplataforma e documente bem as diferenças para ajustes rápidos.

Desarrollar multiplataforma no es escribir una vez y olvidar, sino escribir y saber adaptar. Combinar herramientas adecuadas, diseño adaptativo, pruebas constantes y un buen flujo de integración te permitirá mantener tu proyecto en marcha y superar los problemas de compatibilidad .

Having worked in international teams with diverse tech stacks and devices, I’ve realized that compatibility issues are more about coordination and iteration than just writing platform-aware code. Being proactive, flexible, and open to compromise is what keeps the project moving forward — without sacrificing quality.
