Roll Back The App?

Hi

Is there any way to roll back the iOS app back to the previous version?
I ask, because I still have issues with connecting my iPad and iPhone to the drive, something that I didn’t have with the previous version. After making a previous post re this, and doing some home testing, it seems that the app (which sometimes connects, but often doesn’t) seems to work fine when I’m not at home, which points to a home network issue? but I can connect via my laptop and desktop when at home, it just appears to be the app that is very intermittent .

Thanks

@Pip have you contacted support?
