Device and System Name

Galaxy s20 FE 5G Android 13

App Version

2.0.4-Canary.28

Description of the Issue

Hiya, so basically, for a while since I have installed nightly version of openutau mobile up until now with the new "2.0.4-Canary.28" version, I have had issues with importing ust's and ustx's? importing audios and midis were working but "import tracks" never worked for some reason? It never shows the file menu? idk if that's an issue or if it is done with settings? but here are the pictures, please explain to me what is happening. Thank you.

您好，我之前一直使用 OpenUTAU Mobile 的 nightly 版本，直到最近升级到最新的“2.0.4-Canary.28”版本，但导入 ust 和 ustx 文件时遇到了问题。导入音频和 midi 文件都没问题，但“导入音轨”功能却始终无法使用。文件菜单也一直没有出现。我不知道这是程序本身的问题，还是设置方面的问题。以下是截图，请帮我分析一下问题所在。谢谢！

Steps to Reproduce

1. Make a new song on OpenUtau Mobile
2. Import track

The Import Track feature hasn't been implemented yet, as OpenUtau Mobile 2 is still in development.
