Free trial for real?

Not sure if this is what's supposed to happen or if I'm doing anything wrong, but this extension does absolutely nothing for me. I just installed it yesterday and as soon as I enabled it, all I see on instagram is this box in the lower left-hand corner that says "Video Scrubber: Trial Expired", which is apparently a link. When I click it, it takes me to the support/license purchase page, itself clearly stating that the extension is free for the 1st month and that I have to purchase a license to continue after that, yadda yadda, just like it states here on AMO.

But that's not my issue with it. I already knew that going in, not a gacha or anything. The problem is that I have not been able to use it AT ALL, not even once, to test it or anything. Absolutely NONE of the features work, I can't pause/play with space, there isn't even a seek bar, nothing. It's as if the extension thinks I have already used it for 30 days when in fact I haven't at all. I have confirmed this multiple times by disabling/re-enabling, re-installing, I tried everything. I'd gladly pay for it if I knew it actually worked and I liked the features, I mean it's only $1.50/yr. But as it is, I honestly don't know anything.

I get it, developers need to make money, but switching a free extension to a paid annual subscription one is such a crap move. This one should have been kept free and then a new paid "pro" version should have been added for people who might want whatever future features the developer claims they may add someday.

Became trialware...
Just using Video Controls for Instagram extension instead now since it's free and does the exact same thing.

Trialware really? For a simple scrubber? I got the extension before payment was required, but I'm not interested in your free key when I can write a similar userscript for myself in 15 minutes.

Uninstalled.

Paid extension for browser? =)

Ive been using this for a year, and now i gotta pay for it. Yeah no thanks

about 6 months using it... but for some reason... now is paid...

Bait and switch - this add-on has silently switched to being a paid add-on. Uninstalled. In my opinion, if they are willing to surprise users with sudden fees, they are probably willing to try other dishonest tricks to make money.

pay 2 use with no mention

was useful until they recently switched it to a paid service without notifying or mention it to anyone. pretty unsavory tactic imo. uninstalled.

EDIT: FOUND A REPLACEMENT! Search for "Video Controls for Instagram by David Cavar"
