Unfortunately, I haven't been able to get my hands on a malfunctioning device while the problem is occurring. I got to see Kozball's android tablet but the first time he tried the email link while I was there it worked fine and he was able to squad. *Shrugs*
My IT side wants to recommend the following:
-Clear your cookies and internet cache (saved passwords, etc), restart your browser by closing all open windows (and wait a few seconds), then re-open the browser and try again.
-Try a different browser.
-Try a different device.
If you have the problem across multiple browsers (with histories and saved data cleared) or multiple devices it likely eliminates your hardware and software as the issue and it's something wrong with Practiscore. (Because it's highly unlikely you'd have the same problem with multiple browsers or devices unless you set every single thing up with the same bad settings)
If the problem doesn't persist across multiple browsers or devices, the problem lies with the way your software or hardware is configured. I wouldn't be able to know for sure where the problem lies without seeing it in person.
Hope this helps at least one person. Sorry you're all having trouble.
