I'm trying to attach some files, shared with me in Google Drive, to an email by using my iPad.
It looks like I can not find that files when searching them from the dialog it is shown to select the files to attach. There is no problem if the files that I want to attach are from my Google Drive (instead of shared with me).
It looks to happen the same when I try to make that search from the ios Files app directly. Of course, if I try to make the same search from Drive app, I can find all files and open them.
Please note that all apps and iOS are up to date, and I have only one Gmail account set up on the Drive app.
I'm not sure if that problem id due to a misconfiguration or a limitation of the Apple Files app. In that case, is there a workaround to make me able to attach multiple files shared with me through Google Drive? Probably a workaround could be to copy that shared files to my private Drive or to store them locally on my iPad, but because they are dynamic files, I could not consider that as a solution.
With my old iPad (not using Files app to make the file selection when attaching files) that was not a problem, and I could do that with any problem.
PD. I'm using Apple's Mail.app, not Gmail.app.
