I second this, please. I can't even update the preinstalled apps I use on my 2018 Samsung TV because they keep adding more default apps and there's literally zero free space with nothing but their default apps installed.
I combined a bunch of awful "tech tips" websites into a working approach:
1. Reset my TV to factory settings.
2. Go into the "apps" item while it desperately tries to update itself
3. Go into "Developer Mode" by pressing 12345 on the remote.
4. Restart the TV by holding down power button for 2 seconds.
5. Open "Apps" again
6. Open the cog.
7. Under the app you want to remove, press "Deep Link Testing" and then hit cancel.
8. If the "Apps" app hasn't been updated yet, your delete button should magically reactivate.
I was able to delete the product manual which is like 90mb, all others were reloaded after another restart though but it gave me enough wiggle room to update and install other apps.
As a tech literate person, it was by far the most infuriating experience in recent memory, but achieving some level of victory was fun! Reminded me of hacking my xbox as a teen.
