Both applications give the "Unfortunately, Google Play Store has stopped working." or "Unfortunately, Gmail has stopped working." I do not know if anything has updated in the last day or not. Gmail will give me the notifications of new messages but when I tap them, the error appears and I get nothing. I also get notifications for app updates but when I tap them, the Play Store starts to open and then displays the message that's all. I can only click OK to close. I've tried reboots, clearing caches and data, and nothing. Other apps seem to work fine. Thanks in advance for any ideas.
