New Synology DS118 NAS and old playlists

[MinimSG54]

Hello,

1)
I just replaced my Synology NAS 213 with a Synology DS118 NAS.
I installed Minimserve 2 on the DS118 NAS because my library is on the NAS.
On my smartphone I installed BubleUpnP (which I already had). Unfortunately it is no longer possible to use the old playlists? Is it possible to update them? And in what way?

2)
I am currently using Minimserver in its Starter version and would like to subscribe for one year. I looked for how to pay without succeeding? Please give me a link?

3)
I had successfully installed MinimWatch a few years ago.
I tried to download the software, but no luck.

There you go ... Not speaking English, I used Google Translate to translate French into English. I hope you will understand me and can give me the answers to the above questions.

I'm counting on you because I really appreciate MinimServer.

Thank you .
