When Tor not active, adding a RSS feed fails with unclear error message
If the option to connect to internet only when charging is set, feeds cannot be added or there will be an error message (which content I don't have at hand, but doesn't clearly tell what the issue is) and suggests trying again, which will result to the same problem.
The solution is to either uncheck the option or put the phone to charge and it will be able to add feeds without issues.
I think #2247 would be a potential solution to this, but having the error message say that connecting to internet or unchecking the box is required.
