Render isn’t working

I’ve recently lost Render. Goes straight to home iPad page. I’ve reloded several times. Any hints, guys?

This is also true for me. Sculptura Pocket on an iPhone 12 Pro (iOS 14.3) I get to the share sheet, but if I choose Save Image it doesn’t, but instead dumps out to the Home Screen. Sometimes when it does this it will remain running in the background, and sometimes it will close. Sharing to an app like Instagram does work on iPhone however. Sculptura on an iPad Air 2020 (iOS 14.3) dumps to Home Screen without displaying share sheet. Both apps on both devices behave this way regardless of model complexity.

Fantastic app, but this bug is frustrating.
