Try deleting and re-installing AdAway. Hopefully that'll remove the symlink. (That symlink option should probably be removed).
Our you can do a dirty flash of your ROM
Tried both. No matter what i do, i still get ads. I have the following on my Oneplus 6t running the latest rom:
- magisk 19.3
- systemless hosts module enabled
- symlink of /system/etc/hosts -> /data/data/hosts (this seems to be from the module rather than due to adaway)
- Adaway 4.2.6 installed
- cannot enable the Systemless hosts checkbox in Adaway, every time i try i just get a toast notification about Magisk granting Adaway permissions and then nothing else
- target hosts file set to /system/etc/hosts
Using a file manager i can see that /data/data/hosts has a bunch of entries but this doesn't seem to be picked up. Can see ads in Chrome, Firefox and apps where i wasn't seeing them before.
