Hi all.
Almost same scenario for me: free account, and Domain Subs allways growing up, but never down.
If I unsubscribe manually from subscription overview, it never grows down.
Subscribe screen shows empty (because no active clients), but my quota Domain Subs keep showing 31/250.
So for me, the last engine update is not working, or perhaps I’m doing or undestanding something wrong.
ONE CLUE: perhaps something related with Retained daa ??? Hmmm!?!. I mention this, because I use Retained data on more than 27 of my topics!!.
UPDATE: LAST TESTS:
TEST1:
add a new topic
publish a non-retained topic-value
verify that QuotaDomainSubs incremented by one
delete last subscription from subscription overview screen
Result: QuotaDomainSubs doesn’t DEcrement by one
TEST2:
add a new topic on a Device
publish a non-retained topic-value on that Device
verify that QuotaDomainSubs incremented by one
delete Device from device overview screen
Result: QuotaDomainSubs doesn’t DEcrement !!
Hope some aditional findings or updates will come.
Feel free to ask me some testings by my side.
Best regards from Seville SPAIN.
