Why does this happen using Blocs? Very Annoying

I’ve have paid for Blocs v3 months ago. Periodically I’m asked to supply license key and email that I used when I purchased Blocs. Annoying. What is more annoying is I lose some preferences, google fonts added, etc. when I supply the purchased license key and email address. I’ve purchased software all my life, but this is the first that resets software back to default, losing personal preferences and fonts already set. Any explanation of why this occurs? Thanks

I haven’t seen this issue myself (or seen anyone else mention it), the best thing to do is message support directly and report the issues you are having.
