Congratulations! You've described the universal experience of using cross-platform frameworks.
They can be great as long as you and your customers stay on their most well-trodden path. But as these frameworks grow and become more byzantine, and as your project requirements start reaching for more rarified features and your customers start using new and differing runtime platforms, maintenance overhead starts to dominate and you find yourself running into invisible walls that make it hard for you to deliver on your project roadmap or satisfy the support standards you want for your customers.
This has always been the case for these frameworks, going back many decades, but especially since the explosion of efforts to build them around web stacks, which are easier for developers to use but harder for framework designers to keep sufficiently robust and capable as they age.
There's no free lunch when it comes to targeting multiple platforms. It sucks to have to maintain separate iOS, android, and web apps, and it also sucks to use a cross platform framework.
But I still feel in the end that for many CRUD style apps it's worth it to deal with react native's problems, especially if you can also have significant code sharing with your web app.
If you're trying to build the next snapchat or tiktok you'd better go full native though.
