If you find that after a weekly maintenance, or more generally, you are running into issues such as a block delay error message, the inability to submit battles, etc., clearing site data can often be the quick fix for these.
Desktop Browsers
Step 1: In your browser, right click on Splinterlands and select Inspect/Inspect Element:
Step 2: When the dev tools tab opens, on the top bar select Application:
Step 3: Click Storage on the left hand side, then make sure to select the "Including Third-Party Cookies" option if initially unchecked, then click Clear Site Data:
After this, it may be good to log out and log back in to Splinterlands, and do a hard refresh (Ctrl+Shift+R, or Ctrl+F5), but this should have corrected any issues.
Mobile Devices

Alternatively, click and hold on the browser icon, and when the menu below appears, click the icon in the corner:
In the App Info menu, select Storage:
Then click Clear Data and Clear Cache, and you should be good to go:
