Alternate between wi-fi and phone data for your connection

If you’ve just restarted your phone and the app still doesn’t work, perhaps wait a bit longer to allow your phone to connect online. Sometimes, when you’re on wi-fi and it isn’t connecting, you may have to toggle to phone data and back to get it working, as there could be a hang-up preventing your wi-fi from connecting. The same goes for phone data, if that’s what you prefer or normally use.

Update your phone to the latest version

To keep your phone secure, your phone should always be updated to the latest patch.

If you don’t like the changes to the app, you can always take it up to the app company, and if enough users agree with you, they might make the changes.
