Allow older iOS versions to use Spark but with reduced capabilities.
Older phones running older operating systems still work well, and not everyone has the means, or need, to update their mobile device. While updated apps provide a way to increase and streamline productivity when app support disappears suddenly users with older devices can be drastically negatively impacted.
I use Spark almost daily and do a lot of my work from my mobile device; unfortunately, on April 1st, 2021, when I went to open a project I found app support for my iOS had disappeared. This resulted in a lack of productivity accomplishment.
The ability to use an older version of the app, compaitable with my iOS, would be awesome until I can upgrade my mobile device.
