With this Outlook "feature" my app is almost unusable with Outlook.
In my app:
User receives an email with a link to launch my app
User clicks the link and my app opens up with Outlook
My app starts with OTP screen and OTP is sent as an email to Outlook
User launches outlook and see the OTP (by now my app is closed)
User again click the link and my app is launched with a new OTP :(
End user will never believe it's an Outlook issue, for them the issue is with my app.
Yeah, this is really annoying! And I only have it from an end user's perspective!
If I click a link from Marktplaats (Dutch eBay) it opens the app IN Outlook and shows me the found adverts. Then I have to go back, back and back to get back to my E-mail/Outlook. If I just go to a different app and later on open Outlook again it looks like
it doesn't open Outlook, but opens that Markplaats app. Now, I know that it is within Outlook, but I can definitely understand that some people would get confused.
