I purchased the year ad free sync pro for $16.99 the day it launched. I wanted to support what seemed to be a great app for a new platform even though that was an excessively steep price.
At this point I wish I hadn't wasted my money.
After the last app update every time I opened the app it would crash. I attempted to clear the cache, clear the data, then reinstall the app. It would crash every time I tried to restore my backup. I reached out to the developer first and told them my issue. They initially replied back and said they would look into it and I provided extra information. Went several days with no update and I attempted to contact them again and got no response. I then asked for a refund because it doesn't recognize that I purchased the Pro upgrade. Again no reply. I then tried to get a refund through Google and also no luck and that I should contact the developer.
I will never again purchase sync pro for lemmy or any other platform and I would caution anyone else from spending an arm and a leg for this app when there are plenty of equally good alternatives.
Tried that, too. It says no purchases found. That's when I attempted to contact the developer.
Did you have more than one Google account on your phone? It could be that it's trying to restore the purchase from another account than the one it was purchased from.
I made sure it was done under the right Google account.
You should have a trace of the transaction somewhere in https://payments.google.com under either Activity or Subscriptions & Services.
I don't have any problem showing proof I have purchased Sync Pro.
I attempted to request support first and received a quick initial reply about my problem. Never got an update so I requested a refund in the same email chain and still haven't heard back. I then went through the Google Play refund process and they said they won't refund me either.
So I'm just out my money. No big deal, and I moved on. I just posted so if someone was looking into paying what I think is a ridiculous price for a year of ad free and some features, there was some good feedback.
Just saying that there could have been some kind of payment issue, it's better to ensure everything is fine on that front first. Anyway I bought the lifetime adfree and I'm happy with it, although I don't use it as often as the mobile web-UI since I can't do most of the instance admin stuff through it.
I'm very glad that you're happy with your purchase.
