What platforms have the fastest 3rd party app approval process?
I built an Airtable app and it took 3-4 months from the time I submitted until it was approved and live on the site. Slack was faster (only a few weeks IIRC) and Procore took a couple months as well.
What platforms (preferably fast growing ones), have you been pleasantly surprised about how fast they work with small partners?
Back in the day, Google Play used to let you upload an APK the same day you created an account. Probably takes a little longer now with all the paper work requirements.
Recently I had a look at building a Xero plugin, and it seems like it'll take three months to get approved. Groan!
