We were actually working on some cool new features the last couple of months (like iPhone X Support and Runtime Screen Orientation Changes with our latest release), which postponed offline installer builds. We however provide custom installers to users as part of our support packages, if an offline installer has high priority for you, please contact us at firstname.lastname@example.org.
if your connection is poor, you can try to download and install at different times of the day / at night. We’ve seen connections work better at different times of the day. Of course this also depends on your country and the network.
We currently do not have a pure offline installer in place. However, we can prepare a custom offline installer for users on our paid subscription plans as part of our support offering. Let me know in case this is interesting for you.
We can prepare a custom offline installer as part of the included support of Felgo Enterprise and Indie. The pro plans cover all Felgo core features and plugins. To get Indie, you can upgrade your account with the order process on our pricing page.
