We don't support these type of set ups with apps that control access. The expectation for a child is a dedicated uploader device only used for that purpose. Android 10 is a lot more restrictive on what runs where and when, you may find a way of whitelisting the uploader app.

We have had same kind of observation with Nokia 5/Android 9/640G. No parental control what so ever is used. After upgrading from v0.61 to v0.71 the uploader did not connect automatically when glucometer plugged in. If uploader was already open it crashed (or went to background, disappeared) when plugging in. Connection started to work when reopened uploader. Now we are back to v0.61 which works nicely.
