On the PC, using the browser, it sometimes allows me to select the location, but not always.
The search words are ignored, results shown are considered by Ebay "close enough": if I search "emitor", I get shown results like "emitter". The problem is that I expect 1-2 hits for "emitor" per month, while "emitter" will show hundereds of results, which don't interest me, but make the "emitor" results hard to find.
On the Android app it is even worse! The location option can be selected, but then no options are shown - just a white empty tab, where options like Germany, EU, US, etc. should be shown. This is not a problem on this particular phone, as it happens on the two phones I use.
I guess that one reason for my reduced "user experience" is the fact that I am physically located in Portugal, but use the German Ebay (because I trust German sellers more than those from other EU countries - just my opinion - I have good experience with UK and French sellers, though, but UK now has customs and it is difficult to find the french listings due to lack of knowledge on the correct keywords).
