    Would love a fix for this in 2021.1 also as after updating to 2021.2 we discovered a couple of other issues with our app already and we would like to get this fix in asap.

    I am using 2020.3.24f1, but many users are in trouble because of this bug.
    If the S Pen is not supported, the store reviews will be lowered and it will be directly linked to the sales of the app, so it would be helpful if you could support it as soon as possible.

    Please fix ASAP for 2019.4.x LTS as our player base is asking for the S pen support.

    Just chiming in with the other commenters to request fix on v LTS 2020.3.x - player base very unhappy about the lack of support for the s-pen and we do not want to roll back.

    Since updating project to LTS 2020.3.20f1 (we skipped 2020.3.19f1 update) we found out how many players are actually playing using S-Pen as we got many negative reviews on store page, support tickets with this topic and many reports in our Discord community (actually so many that we had to put this as a separate answer into FAQ). Having this fixed for 2020.3 LTS would be very nice as we don't want to roll back project.
