Terrible app, I used on regular basis to make donations to pet rescues and fire depts, then suddenly I wasn't getting code they sent. I msgd them to no avail. They said they don't send codes?! And there's option to pay without code so tried that several times. Putting in all info only to get msg that my email already has an acct.! Well duh! So now I can't partake in rescue fundraisers that mean a lot to me. But no one at square tried to solve the problem.
