Thank you for using RVWeather.
Love this but for the last several weeks the email has been 10 or so days old. Today 12/12 I received 12/3. What’s up?
Hi Liza! Glad you like the forecasts. You are the 2nd person recently to tell me about this problem; it appears there is an issue between my mailing system and the @me.com (old Apple) accounts. The other person used his @icloud.com account and that solved the issue. I will also ask my mail provider if they have seen this issue more broadly, and if they any a solution. Thanks for letting me know! Best, -Dave
