Thanks for the detailed response.  I got lucky and was able to get my transaction accelerated through viabtc, and it was confirmed an hour or so later.  Good to know how to handle CPFP if I need to do this in the future although it's frustrating that Glidera is still not including an appropriate fee, especially since they do not give the user any control over this.

Also been waiting on purchase transactions from Glidera that were suppose to arrive days ago.  No response from support.  Would be interested to know if anyone else has purchased through Glidera recently and has had delays receiving their deposits.
