A. Check your internet connection to ensure it is stable and strong. If you are on Wi-Fi, try switching to mobile data or vice versa to see if performance improves. Additionally, close any other apps running in the background that may be consuming bandwidth.
B. If performance issues persist, try clearing the app's cache. Go to your device's Settings > General > iPhone Storage, find the Waterstones app, and select 'Offload App' or 'Delete App'. Reinstall the app from the App Store to clear any cached data that may be causing slow performance.
