9.0 pie – Play Store not updating some apps

On my Samsung Galaxy Tab S2 running LineageOS 16 with Opengapps, some apps are not being updated to the latest versions. In particular there is Google Meet and Sheets. Meet is stuck on a version dated August 2020 whereas my phone offers a version dated November.

I tried installing Aptoide apk store and it offered updates to both of these apps (and some other too). I installed them and they work, so it is not a question of incompatibility with my system. However, I would like to stick to the Play Store.

Why is this happening? And what could be done to get the latest versions?
