Issue on mobile

My obsidian is in date, then installing Harper would make my obsidian to stop. I would go back to obsidian to find that Harper is installed but can't enable.

Start by reproducing the reported installation and enablement failure with an up-to-date Obsidian installation and Harper on mobile. Record the device and versions, determine whether Harper installs but cannot be enabled, and document the steps and expected behavior needed to consider the issue resolved.
