Old Ipad and Tesco Delivery Slots

Hi andyhind, thank you for posting in Apple Support Communities.

I had a similar issue with my Woolworths groceries app (not sure if you are using an app) but I then logged into the website version on my ipad using safari and managed to get the same results as you did on your Mac.

You could also try updating your iPadOS which is 15.3.1 (if you have not done this already) as updates can help resolve some problems. The following link can help you:

And a ‘Force Restart’ may also help resolve the issue as per the following link:

Then the only other suggestion I can offer is to check if the app needs updating and/or delete and reinstall the app as per the following link:

If the issue persists and is not resolved by the above support articles, you can make an appointment and have your iPad inspected at an Apple Store or AASP (Apple Authorized Service Provider). Please use this link to find one in your Country Apple – Location Selector. After going through the process, you will be given all the options available.

You can also contact Apple Support as follows:

• Online:--> Genius Bar Reservation and Apple Support Options - Apple;
• Contacting a local Apple Store or AASP among the list provided above but also again as follows Apple – Location Selector; or
• Using the "Apple Support" app, available and downloadable from App Store. 

From your post I infer that you may be accessing Tesco’s online services using a web browser (such as Safari).

Are you using a recent model iPad - with an up-to-date version of iOS/iPadOS? If not, this may be the root of your problem - as the Tesco website may be expecting a modern web browser. Older version Operating Systems and/or browsers may not be supported by the retailers e-commerce servers.

If you are using a recent version of iPadOS, ensure that your iPad is operating in is “desktop” mode with the retailers website.

Some websites incorrectly identify your iOS/iPadOS Safari User Agent when used in one or other of its browsing modes - of which there are two - these being Desktop and Mobile. Misidentification of the browser Agent can often manifest as the website reporting that your browser is out of date, or won’t properly render a page.

It’s easy to switch between modes if a website isn’t functioning correctly. From the desired web-page, touch the aA icon at the left of the Address Bar; this will reveal a menu. From the menu select Website Settings, then select (or deselect) Request Desktop Website, then tap Done. Now refresh the webpage.

The chosen setting will be saved for the selected website - and can be simply reversed if needed.
