We are sending an email to everyone now with all the details (may take through tomorrow for all to send) but short version:
Existing active, self-hosted licenses will have email support until 1 January 2022 or their current renewal date, whichever is later. After that, it will be community support only.
We will of course still always help you and if we cannot sort out issue here on our community, we will take your post to email and work with you in private. You have probably seen a lot of us saying "I will submit a ticket for you." We have an integration between our community here and our help desk (via our Zapier integration) so we can quickly do that.
So think of it as support starts on the community but email support is still there if we cannot help you in public. Of course billing/account questions can always be done in private by email.
Actually you went from $85/6 months or $170/year to $250/year. That's an increase of $6.67/month.
As you can see from the other post I quoted here, 6-month renewals sort of confuse people 🙂. Annual is pretty industry standard. Many clients will add account credits regularly throughout the year to smooth out the costs if they like.
