As you might have already heard or seen from other creators, Patreon is updating how/when payments will be processed later this year.
In-depth info here
The TLDR version is that starting soon you will be charged on the day you subscribe and then that day each month instead of on the 1st. (If you back on the 23rd you get charged every 23rd of the month from then on.)
If you are already a backer it will default your payment day to the 1st so nothing will change. It should only affect new or returning members. Due to this change rewards will be sent out on the 1st of the month and then each friday for the rest on the month to account for pledges processed later in the month. If you'd like to ensure getting the new minis as soon as they are available make sure to back on the 1st or 2nd of the month.
MyMiniFactory's Tribes will remain the same monthly cycle with instant rewards. So if getting the models right away is important to you, consider switching over if you aren't a long term subscriber. We get the same amount of support from either platform so choose what works best for you!
