Hi @coffeecraig, as far as I know this is not normal. I see that “Placeholder” is mentioned - this implies to me that the TWRP app is not installed at the moment, but as you cannot remove it, something must be installed, presumably as a “System app”. I do not think this was deliberate by Easy Installer team.
Here is a suggestion to investigate. Please go to
Settings > Apps and notifications > See all apps > 3 dot menu, top right > Show system.
There is a search function there, or you could keep scrolling to see if you find anything related.
Once found (it would be interesting to know what you find), tap on the app > Advanced. At the foot of that description you should find the app named in this type of format: com.android.twrp.placeholder.
Assuming it is a system app, and not the actual TWRP app, It should be possible to remove it from your Bliss homescreen by following this method Uninstall default apps - #29 by AnotherElk
Or, if you use a different launcher like Lawnchair 2, you can leave it hidden.
If Easy Installer was definitely responsible, perhaps, https://doc.e.foundation/support-topics/report-an-issue.
