I checked then, but no, I didnt find any previous notice. It is really dissapointed after putting so much work on creating those sites, buying the right modules that they archive it because they considered it not active enough. This is their reply "the store can not be recovered after the archiving. It has been archived due to the inactivity and this is written in our "terms and conditions". It is the normal process which hapen every time. "
I have done many sites with other platforms and never experienced something like this. And never thought I have to read those terms because I believe I can trust they will have good practices. My mistake here. So be careful with the "small letters" with Prestashop, read each of them carefully as with the banks if you dont want to be unpleasently surprised. Even though I got a very nice person in prestashop that help me out when this happen the first time and Im very thankful with her, for sure I will recommend anyone that aks not to rely on Prestashop.
And indeed, I also believe that a lot more people will start complaining about this when more people start to see their sites close. Here is people already talking about this https://www.prestashop.com/forums/topic/547988-prestashop-cloud-discontinued-how-long-do-we-still-have/
