Good Morning! We appreciate your patience, but you would not need to end your subscription. Your issue would be resolved before that and we can extend the testing for you.
Generally, it starts from the time the purchase is made. Nevertheless, you can reach out to us through email at info@techloyce.com and we can assist you with any required extensions to the trial period if required.
It would be better if we get the access, you can setup a temporary password and change it later. Else, please provide some screenshot or a video showing any errors or highlighting what's not working!
We currently do not support 2 way synching for the record creation/update or tags. This will be a custom development at our end. Please let us know if you want this from us and ew can share the effort estimates with you.
