Where can I see my last License purchase? I think I have to update to GS 10?

I’m using GS 9.9.5 (1736)
I have tried all the remedies to get eBay to allow me to post w/o giving me this stupid error message.
I did this>> Step-by-Step Reset

  1. Quit the GarageSale application.

  2. In Keychain Access, right-click and Delete both of the GarageSale eBay Account entries.

  3. While still in Keychain Access, clear the top-right search box and type ebay token. If any generic eBay tokens appear, delete those as well.

  4. Restart your Mac immediately to flush out the system’s memory cache.

  5. Launch GarageSale, go to Settings > Accounts, click the + icon, and log back into your eBay store.

    Then this >>>
    Since resetting the tokens and restarting the Mac did not resolve the problem, the underlying cause is that eBay is actively shutting down the legacy category API used by GarageSale 9.

    NOW it says that I need to do THIS >>>>
    **The Definitive Fix: Upgrade to GarageSale 10
    **
    For some reason I can’t find my last license update and can’t figure out what else to do so the app will work. I can’t upload ANYTHING to ebay!
    It would be great if I could just one time open GS and eBay and use it.

Upgrading to GarageSale 10 is a good idea, yes.
I just checked and found out that you received a FREE GarageSale 9 license back in 2022.

You can use your GarageSale 9 license to purchase an upgrade license for GarageSale 10. This is how:

• Download GarageSale 10:
https://downloads.iwascoding.com/downloads/GarageSale_10.0b21.dmg
• On first start, your data will be copied into a separate GarageSale 10 library (If you switch back to GS9, changes made there will not be visible in GS10 and vice versa. Also, macOS will prompt you for your Keychain password for each of your eBay accounts, so GS10 can access your saved eBay access tokens)
• Once everything is imported, you can try out GarageSale 10
• If you want to purchase the upgrade license, start the purchase flow from within GarageSale 10. (Just choose “Buy License…” from the “GarageSale” menu.)
