Anyone else is struggling keeping the "followed" across several clients?

I'm currently using #nostrudel, #iris.to, #snort.social and #Ametyst:

In particular, I'm following:

* 19 profiles on iris.to

* 11 on #snort.social

* 67 on nostrudel and Ametyst (hopefully they are the same).

Is it a problem of relays? I synced them a while ago and 5 of them are paid ones.
