Have to relink my dropbox account 3 times in a week

Hi

I am having issues with dropbox syncing and it looks CM never fix them

A lot of files from my purchased (free and paid) do not sync proper and this week I had to reconnect my dropbox account to CM 3 times and with no idea why it lost the connection
(PS: Where can iI contact CM to fix individual purchases that don’t sync and even do not download at all (files do not exist)

I was avoiding buying new stuff here because of the never fixed bugs and I made a U$ 100 purchase and my “bonus” was more bugs…
