Also questions below I ran thru AI:
How many devices do you have and how many are on?
I would use 1 device at a time that works.
And do all you devices have same operating systems?
Do all you devices have same browser!

Here goes: might need someone to sit with you to help.

This redirection typically happens because your iPad's browser is trying to use "Universal Links" to open the Facebook app automatically.

To force the browser to handle the location change instead of jumping to the app, try these steps:

1. Use Private/Incognito ModeOpen a Private tab in Safari or an Incognito tab in Chrome. This often prevents the browser from communicating with installed apps, allowing you to click the location and update it directly within the webpage

.2. Long-Press the Marketplace LinkIf you are already on Facebook in the browser:

Don't just tap the Marketplace icon or the location text.
Long-press it until a menu appears.
Select "Open in New Tab".

This forces the browser to stay within its own environment rather than triggering the app.

3. Request Desktop Site

The mobile version of the site is more likely to trigger the app.

In Safari, tap the 'AA' icon in the address bar and select "Request Desktop Website".Once the full desktop version loads, click the location in the left-hand filter column and type your new city or postcode.

4. Update Your Profile City FirstSometimes Marketplace is "stuck" because it's pulling from your main profile data rather than your GPS:Go to your Profile > Edit Profile > Edit Your About Info.Manually change your Current City and save it.

Refresh Marketplace; it often updates to match this new profile city automatically.

5. Adjust iPad Privacy SettingsEnsure your browser actually has permission to see where you are, or Facebook might default to a previous location:

Go to iPad Settings > Privacy & Security > Location Services.Make sure it's On and that your browser (Safari/Chrome) is set to "While Using the App"

Ran your question thru AI:

Even after logging out and using the direct URL,
Facebook may still display an old location due to cached data, IP address tracking, or your phone's GPS overriding the manual setting.

Here are the next steps to force an update, based on your situation:
1. Force Update via "Check In" (Mobile Recommended)Open the Facebook app on your phone.

Start a new post and select "Check In."Search for your new city, select it, and post it.

This forces the server to update your location data.

2. Update "Places Lived" in ProfileGo to your Profile > Edit Profile > Edit Your About Info > Places Lived.Ensure your "Current City" is updated and saved.

3. Clear Cache and App Data (Android)Go to your phone’s Settings > Apps > Facebook > Storage.Select "Clear Cache" (this does not log you out). If that fails, select "Clear Data" (this will log you out, but clears cached location data).

4. Check VPN SettingsIf you are using a VPN, it will override your actual location. Ensure it is turned off or set to your desired city.If the location is for Marketplace, you can manually change it directly in the Marketplace tool by clicking the location button at the top and typing your new location

When you go to clear all, make sure you include “cache”.
