Hmm, might be a page issue, or an itch.io issue? Need to download the APK from the itch.io website, rather than the itch app.
From testing this with a secondary account, there are three ways to access the downloads:
- Visit https://chrisnzl.itch.io/tallowmere – there should be a "Download" link at the top of the page above the title art, or
- Visit https://itch.io/my-collections – find Tallowmere – click the pink "Download" link beneath the thumbnail, or
- Visit https://itch.io/my-purchases – find Tallowmere – click the pink "Download" link beneath the thumbnail.
From these pages, the "Download" link should take you to a unique URL with download links for each version / platform on offer. Looks something like:
Are you able to download the APK this way?
