If a request takes a long time - BOMA's system gives you a timeout error.
Usually however these errors are caused by something blocking all or part of the functionality on BOMA's site. This can be an antivirus or security system, or most frequently it's caused by an ad blocker.
Please add BOMA's app (app.bomamarketing.com) and website (bomamarketing.com) to your trusted sites. Please also ensure they are excluded from any blocking by ad blockers or similar software (e.g. security/antivirus).
